What's this octupus thing?
Pandora is a monitoring tool designed to monitor either systems
or applications. It will allow you to know the status of any of
your systems, whether they're hardware for network communications,
web applications or just an operating system. Pandora is able to
monitorize whatever you want.
Architecture
Distributed architecture
High Availability and Load Balancing
Web administration
Active and pasive monitoring.
We will talk about...
A brief overview of installation.
The software agents.
The modules.
And this only for Linux.
and we are not going to talk about...
SNMP console.
Installation in deep.
About the installation...
The documentation is quite clear, but the process needs to be
made more straightforward.
You need PandoraFMS_Console &PandoraFMS_Server tarballs
because database configuration is packaged in the Pandora_console
tarball.
You need a user called pandora and create ssh keys for the
agents to send de data.
The pandora software agents
Totally customizable (easy shell language):
bash for Linux.
csh for BSD and NokiaIPSO.
ksh for Solaris & AIX.
Free Softare (GPL Licensed), so source code is available to
modify and improve any one of it.
Agent Configuration
server_ip 192.168.50.100server_path
/opt/pandora_server/data_inpandora_path /opt/pandora_agent/temporal
/opt/pandora_agent/data_outinterval 300debug 0checksum 0#if not set
uses hostname#agent_name geminon
Adding an agent in the web console
Agent's modules
Each agent can be defined a set of modules.
Modules can inform the state of the process we want to monitor,
or data about services or system variables like CPU usage, memory,
disk, etc.
Data gathered are transferred in an XML file to the Data Server
using SSH, at customizable time intervals.
XML files are read and data is processed into de Database.
Module Example
module_beginmodule_name disk_root_freemodule_type
generic_datamodule_interval 2module_exec df -kh / | tail -1 | awk
'{ print 100-$5 }'module_max 100module_min 0module_description Free
disk Percentage of root partitionmodule_end
Module Types
generic_data: numeric data type.
generic_data_inc: incremental numerical data type. It stores
data resulting from difference between last agent data and actual
data.
generic_data_proc: Boolean data type: 0 means False, and >=1
means True. Generic Proc types are also called "monitors". They Are
displayed in agent view as little lamps. Red if False, Green if
True.
generic_data_string: Alphanumeric data type (text string, max.
255 characters).
Network Server Module Types
remote_icmp: get network latency in miliseconds for remote
system.
remote_icmp_proc: makes a "ping" to remote system. Report 0 if
system is not reachable or not responding.
remote_tcp_proc and remote_ucp_proc: makes a "tcp" / "udp"ping
to remote systems and reports "1" if a listing port is responding
and 0 if not responding.

Alerts
eMail. Sends an e-mail from Pandoras Server Internal audit.
SMS Text. Sends an SMS to a given mobile phone
SNMP Trap. Sends a SNMP Trap
Syslog. Sends an alert to the Syslog
Conclusion
Pandora is a powerfull Network Monitoring System with all the
advantages of free software.
There are other solutions (Nagios, ZenOSS) but Pandora offers
greater posibilities, wich pays the added complexity.
Being a Spanish development lowers the language barrier, helping
those wanted to get involved.
... at the end...
any questions?
