4 ServerView Threshold Manager

1 IntroductionThe ServerView Operations Manager provides you with the Threshold Man-ager, within which you can use thresholds to monitor one or more of thePRIMERGY servers currently being managed, and any virtual machines run-ning on these servers, from a central management station.

For this purpose, you define thresholds for the different performance para-meters associated with the server being managed. These parameters aregrouped together to form a threshold set that is stored on the server. Here,ServerView agents use the defined thresholds to monitor the performanceparameters. If a value exceeds or falls below a threshold, the ServerViewEvent Manager is notified accordingly.

You can use this threshold set, for example, to monitor the utilization of spe-cific server components on a server that is currently being managed, andthus detect resource bottlenecks in good time.

The Threshold Manager provides a user-friendly graphical user interface forthe creation and assignment of threshold sets to the servers currently beingmanaged.

1.1 RequirementsIn order to use the Threshold Manager to monitor a server from a central man-agement station, the following requirements must be fulfilled:

l General requirements (see "General requirements" on page 5).

l Additional requirements for virtual platforms (see "Additional require-ments for virtual platforms" on page 6).

1.1.1 General requirementsIn order to use the Threshold Manager to monitor a server from a central man-agement station, the following requirements must be fulfilled:

l ServerView Agents as of V 4.90 must be installed on the managedserver.


1 Introduction

l A valid user ID for the managed server must be listed in the user-/password list of ServerView Operations Manager. For further details,please see the ServerView Operations Manager user guide.

After ServerView agents are restarted (e.g. after a reboot or after a newinstallation) it may take 5-10 minutes until a threshold status is reported.

If you are upgrading from ServerView Operations Manager lower V4.90 to ahigher version, it is not possible to configure or even delete old-stylethresholds. In order to remove an old configuration it is therefore recom-mended to either:

l Disable Threshold Monitoring before updating ServerView OperationsManager as of V 4.90.

or

l Uninstall / reinstall ServerView Agents as of 4.90.

A description of the installation of ServerView Operations Manager andServerView Agents is beyond the scope of this documentation. Their install-ations are described separately in the ServerView installation manuals.

1.1.2 Additional requirements for virtual platformsTo use the Threshold Manager for virtual platforms it is necessary to con-figure account information for the virtual system within ServerView VMEagents. In order to do so, the following steps are necessary:

1. Create a system user.

2. Add read-only access to VMware API to this user.

3. Add user to the app.config.xml file.

The following virtual platforms are supported:

l VMware ESX

l Citrix XenServer

l Xen

How to configure the account information for a virtual system is describedbelow using the example of a VMware ESX system.


1.1.2.1 Create a system user (e.g. for VMware ESX)

In our example this user is called "sv_agent".

The user for this purpose should be created on VMware ESX host.

1. Create a user using the user add command.

For extended security this user has no system login opportunity and isnot a member of any linux group.

[root@esx4 ~]# cat /etc/group | grep sv

sv_agent:x:500:sv_agent

[root@esx4 ~]# cat /etc/group | grep users

users:x:100:

[root@esx4 ~]# cat /etc/passwd | grep sv

sv_agent:x:500:500::/home/sv_agent:/sbin/nologin

passwd sv_agent

The password for this user must be acceptable by VMware ESX.

Enter a password that fulfills VMware ESX requirements:

A valid password must consist of at least 7 characters.

A valid password must meet 3 of the following criteria:

l at least 1 uppercase letter (A-Z, English)

l at least 1 lowercase letter (a-z, English)

l at least 1 base 10 digit (0-9)

l at least 1 non-alphabetic character (e.g. '!', '$', '#', '%', ...)

1.1.2.2 Add read-only access to VMware API for this user

1. Login to vSphere with administrator authority.

2. Click View - Inventory.


1.1 Requirements

1 Introduction

In the tree view you see your virtual host.

3. Right-click the host and select Add permission from the drop-downmenu.


4. Select Read-only from the selective list in theAssigned Role section.

5. Select the optionPropagate to Child Objects in theAssigned Rolesection.

6. Click Add... in theUsers and Groups section.

TheSelect Users and Groups dialog is displayed.

7. Select the user name sv_agent in theUsers and Groups section.

8. Click Add.

The name of the selected user is displayed in theUsers field.

9. Click OK.

The added user’s permissions can be checked by visiting thePermissionstab of the Inventory view.

Now this username and password could be written into the app.config.xmlfile instead of root.


1.1 Requirements

1 Introduction

1.1.2.3 Add user to the app.config.xml file

1. Edit the file /etc/srvmagt/VME/etc/app.config.xml.

2. Search for the section titled <authentication>.

3. Fill in user and password information as necessary:e.g. <User>sv_agent</User><Password>pw4SVagent</Password>

4. Save the file.

5. Restart ServerView Agents.

Defined threshold values can only be changed if there is a valid user IDin the user/password list of ServerView Operations Manager. This canbe any user ID on the managed server, not just the access author-izations in the app.config.xml file.

2 Threshold Manager concept

2 Threshold Manager conceptThe Threshold Manager enables users to customize threshold monitoring forPRIMERGY servers. Threshold management supports monitoring for threedifferent server types:

l physical servers

l virtualization hosts

l guest systems

Each of these three server types comprises a server-type-specific set of para-meters that can be monitored using defined thresholds.

To start the Threshold Manager, you have to activate the optionsEnable Performance Monitoring andEnable Threshold Man-agement on theSettings tab.

As soon as these options are activated, the Threshold Manager startsmonitoring all managed servers (All Servers) using the default tem-plates for the different server types.

For how to deactivate threshold monitoring for a single server, see sec-tion "Deactivating / activating performance monitoring" on page 58.


2.1 Monitored parameters

2.1.1 Parameters monitored for a physical server

Parameter Significance

cpuAll (%) Utilization of all physical processors

cpuKernel (%) Utilization of all physical processors in kernelmode

cpuUser (%) Utilization of all physical processors in usermode

storageUsage - <logicaldrive>

File system usage of a logical drive.

For example:

storageUsage - C:\(%)File system usage of driveC:\

storageUsage - /boot (%)File system usage of /boot directory

storagewrite (kB/sec) Write throughput for mass storage

1) The experience shows that if a system is having memory problems, theavailable swap space may be full. We therefore decided to take the total of




physical memory and swap space as the basic measurement value formemory usage. The percentage is calculated as (used memory + used swap)/ (available memory + available swap). Usually, this value will converge to avalue given by the relationship between available memory and availableswap and thus stay below the default threshold. Only if there is a memoryshortage and swap space starts filling up an alert will be triggered.

2.2 Values that can be defined for a parameterYou can define five values for each parameter:

l a lower threshold (Lower Warning).

If the value measured falls below the lower threshold, the systemissues an error message with the following status: Warning.

l upper threshold 1 (Upper Warning).

If the value measured exceeds upper threshold 1, the system issues anerror message with the following status: Warning.

l upper threshold 2 (Upper Critical).

If the value measured exceeds upper threshold 2, the system issues anerror message with the following status: Critical.

l a measuring interval (Measuring Interval).

The measuring interval specifies the time interval (in minutes) betweeneach measurement. It should always be shorter than the threshold


2.2 Values that can be defined for a parameter


interval, so that there are several measurements within a threshold inter-val before the system issues a message.

l a threshold interval (Threshold Interval).

The threshold interval specifies the period of time (in minutes) for whichmeasurements are averaged and compared against the threshold, sothat the system can issue a corresponding message (Normal, Warn-ing orCritical).

Therefore, the thresholds prompt the following actions:

Value Effect

Between 0 and Lower Warning Error message with status Warning

Between Lower WarningandUpper Warning

Error message with status Normal

BetweenUpper WarningandUpper Critical

Error message with status Warning

AboveUpper Critical Error message with status Critical

2.3 Definition of a threshold setSince you generally want to monitor several server parameters, you sim-ultaneously define all of the thresholds for the parameters to be monitored.The threshold definitions for the parameters to be monitored are groupedtogether in a set known as the threshold set.

There are two ways in which you can define a threshold set:

1. You can define a specific threshold set for one server. This type of defin-ition is known as a server-specific definition.

2. You can assign a name to a threshold set and then save it. You can usethis set to assign the entire set of threshold definitions to one server orto a group of servers. These predefined threshold sets are known astemplates. The templates are stored and managed in the template areaof the Threshold Manager.

2.4 Definition of a templateYou can define a threshold set for a server type and assign a name to the set.You can then use this set to assign the entire set of threshold definitions toone server or to a group of servers. Such a predefined threshold set is knownas a template.

Since the range of parameters that can be monitored differ according to theserver type (physical server, virtualization host or guest system), there arethree template categories (see "Creating a new template" on page 61).


2.3 Definition of a threshold set


2.5 Definition of a standard templateYou can define a template as a standard template for a particular server type.In total, you can define three standard templates as follows:

1. a standard template for physical servers

2. a standard template for virtualization hosts

3. a standard template for guest systems (virtual systems)

The standard template is then automatically valid for all servers of the rel-evant type, for which an additional threshold set has yet to be configured (see"Defining a standard template" on page 67).

2.6 Sample templatesSample templates are delivered with the Threshold Manager. The followingtwo sample templates are available for each server type (physical server, vir-tualization host, and virtual machine):

l a template for monitoring the load (I/O and CPU)

l a template for monitoring energy consumption (alarm when the CPUload falls below a certain level)

The sample template for monitoring the load is defined as default template foreach server type.

Figure 5: Load2

Figure 6: Energy2


Default templates for virtual machines (Load3 / Energy3)

Figure 7: Load3

Figure 8: Energy3


2.6 Sample templates


2.7 Ranking of different threshold definitionsYou can define a server threshold on three different levels:

l by defining the thresholds specifically for the server

l by assigning a suitable template

l by defining a standard template for the relevant server type

In other words, you can simultaneously define several definitions for aserver. However, only one definition is valid for the server. Here, the rankingis as follows:

1. the server-specific definition

2. the template assigned to the server

3. the standard template for the server type

Examplesl If a template is assigned to a server group, but a server-specific defin-

ition already exists for a server in this server group, the server-specificdefinition continues to remain valid for this server.

l If a server is added to the server list under theAll Servers server groupand there is still no special configuration for this server in the ThresholdManager, the threshold is monitored using a standard template for therelevant server type.


3 Threshold Manager main window

Figure 9: Threshold Manager Main Window

The main window contains the following elements (from top to bottom):

l The ServerView Suite header.

l The ServerView Suite menu bars.

l The work area, which is divided into a navigation bar on the left and anwork area on the right.

The navigation area on the left contains a tree structure. The view selectedhere determines the content shown in the work area on the right.

If you click Settings, there is no tree structure in the navigation bar onthe left.


2.7 Ranking of different threshold definitions


3.1 The tree structure

Figure 10: Tree structure

In the Threshold Manager, the tree structure contains servers or existing tem-plates. You use theServers and Templates tabs to control the content of thetree structure. The selection you make in your tree structure controls theview displayed in the work area on the right.

If you click Settings, there is no tree structure in the navigation bar onthe left.

ServersIn theServers view, the tree structure shows the servers contained in theServerView server list. The tree structure is divided into two differentgroups:

Group Significance

All Servers Predefined server group. The servers listed in thissection are all servers which are managed in Oper-ations Manager.

Groups Customized server group, which you created withthe ServerList application


The icon that precedes each server shows a composite threshold statusof the parameters for which thresholds and monitoring values are defined(see "Values that can be defined for a parameter" on page 19):

Icon Significance

OK: Average value is between Lower Warning andUpperWarning.

Warning: Average value is between 0 and Lower Warning orbetweenUpper Warning andUpper Critical.

Critical: Average value is equal or greater thanUpper Critical.

Unknown: Parameter value is not provided by agent software.

Processing: Calculation is in progress.

Not Available: There is no connection to the agent.

This may also happen due to timeouts in the event of resourceshortage.

TemplatesIn the Templates view, the tree structure shows existing templates. Itcontains theAll Templates group and three additional subgroups:

Group Significance

All Templates Predefined template group, which, in turn, containsthree additional predefined template groups

3.3 The server viewYou open a view for a particular server by selecting a server, VM host or a vir-tual machine in the tree structure in theServers view or by clicking on anobject name in the server list.

In the view for an individual template, you can create a new template orchange an existing template.

Figure 12: Server view

The view for an individual object (server, virtualization host or virtualmachine) is divided into the following three areas:


l a header that contains the status icons from the server list and theobject name

l a selection area in which you select the definition type: a server specificdefinition or a template based definition

l a table containing object parameters, which can be monitored using theThreshold Manager

Server specificDefinition of a server specific threshold set

Template basedDefinition of a threshold set based on an existing template. The selectionlist contains all of the templates already defined for the current objecttype. You can select a server template and use it without making anychanges or you can customize the server template. In the latter case, youmust click onUse As Server Specific after you have selected the tem-plate you require.


Column Significance

Icon Parameter-specific threshold status

Parameter Parameter for which thresholds and monitoring val-ues are defined. The list of parameters differsaccording to the server type for which the templateis defined.

Threshold interval The threshold interval specifies the period of time(in minutes) for which a value, on average, exceedsor falls below the threshold, so that the systemissues a corresponding message (Normal, Warn-ing orCritical).


3.3 The server view


Column Significance

Measuring interval The measuring interval specifies the time interval(in minutes) between each measurement. It shouldalways be shorter than the threshold interval, sothat there are several measurements within athreshold interval before the system issues a mes-sage.

Lower Warning Lower threshold as of which a warning is reported

Upper Warning Upper threshold 1 as of which a warning is reported

Upper Critical Upper threshold 2 as of which a critical warning isreported

Average value Average value over the last measuring interval


To disable the threshold monitoring for one parameter, set bothMeasuring interval and Threshold interval to 0.

The table contains the following columns:

Columns Significance

Parameter Parameters for which thresholds and monitoringvalues are defined. The list of parameters differs inaccordance with the server type.

The parameters are described in section "Mon-itored parameters" on page 15.

Threshold interval The threshold interval specifies the period of time(in minutes) for which a value, on average,exceeds or falls below the threshold, so that thesystem issues a corresponding message(Normal, Warning orCritical).

Measuring interval The measuring interval specifies the time interval(in minutes) between each measurement. It shouldalways be shorter than the threshold interval, sothat there are several measurements within athreshold interval before the system issues a mes-sage.

Lower Warning Lower threshold as of which a warning is reported

Upper Warning Upper threshold 1 as of which a warning is reported

Upper Critical Upper threshold 2 as of which a critical warning isreported


To disable the threshold monitoring for one parameter, set bothMeasuring interval and Threshold interval to 0.

3.6 Settings

Figure 18: Settings view

In theSettings tab you activate / deactivate the performance monitoring andthe threshold management. You open theSettings tab by clickingSettingsin the navigation bar on the left.

If the optionEnable Threshold Management is deactivated, theServ-ers and Templates buttons are disabled.

Enable Performance MonitoringYou can activate or deactivate the performance monitoring.

If the performance monitoring is deactivated, performance data are nolonger collected from the managed servers. As result you cannot see theperformance history in the history chart in the Single System View ofServerView Operations Manager.

Enable Threshold ManagementYou can activate or deactivate the threshold management.


If the threshold management is deactivated, the following Operations Man-ager activities will be switched off:

l Threshold data and status are no longer collected from the managedservers and no configuration synchronization is performed.

l SNMP threshold traps will be ignored by Operations Manager.

l TheServers and Templates buttons in the navigation area on the leftare disabled.

IMPORTANT

1. This does not mean that, if the sending of SNMP traps isdeactivated on the agent side, Operations Manager willignore only these traps.

In order to fully deactivate threshold traps, please selectthe target servers in the server list of the Threshold Man-ager and then click Deactivate.

Consider configuring a valid system user account inSVOM-Administration -Users/Passwords before proceeding.

Note that theServers and Templates buttons in thenavigation area on the left will be disabled as soon asthe threshold management is deactivated. So if youwant to deactivate the sending of SNMP traps on theagent side, please do so before deactivating thethreshold management.

CAUTIONThis will deactivate the sending of SNMP traps on theagent side for all Operations Manager instances. It is cur-rently not possible to disable the sending of SNMP trapsfor specific Operations Manager instances.

4 Working with the Threshold ManagerIn order to be able to use thresholds to monitor the performance values of aserver, you must define a threshold set for the server at the central man-agement station. You can define threshold sets for the following servertypes:

l physical servers

l virtualization hosts

l virtual machines or guest systems

You can define a threshold set for a specific server or you can use a templateto assign a threshold set to the server. You can also define a threshold set asa standard threshold set that is automatically assigned to each server of thesame type as long as you have not made any additional definition or assign-ment.

The threshold set is stored on the server. The ServerView agents use thedefinitions to monitor the performance parameters of the server and to reportan event to the central management station when a corresponding eventoccurs.

4.1 Opening the Threshold ManagerThere are two ways in which you can open the Threshold Manager in theServerView Operations Manager:

l On the start page of the ServerView Operations Manager, chooseEvent Management/Threshold Manager.

l In the ServerView menu bar, chooseEvent Management/ThresholdManager.

To start / operate the Threshold Manager, you need the appropriate per-missions. As the RBAC (Role-based access control) based user man-agement of the ServerView Suite controls the assignment ofpermissions to users by means of user roles, please ensure that youruser role is equipped with the required privileges. For details see the"User Management in ServerView" user guide.
