Installation

To retrieve all the data from Tomcat you will need:

The role needed for the plugin to get the information from Tomcat is “manager-script”:

<user username="user" password="password" roles="manager-script" />

All the information is retrieved from the Tomcat manager application. Is mandatory to have it
enabled in order to monitor the service.

http://<Tomcat-IP-Address><Puerto>/manager/status?XML=true
http://<Tomcat-IP-Address><Puerto>/manager/text/list

Note: Tomcat’s default TCP Port: 8080

In case you could find any issue connecting to the service, you can add a new connector to the Tomcatserver. Following you can find a configuration example:

/etc/tomcat<version>/server.xml

Pandora FMS plugin for Tomcat service monitoring. Example configuration:

[CONF]
host=localhost
port=8080
user=admin
password=admin
https=0
enable_status_monitoring=1
enable_vminfo_monitoring=1
module_prefix = tc01
agent_name = Tomcat server
agents_group_name = tomcat
interval = 300
temporal = /tmp
transfer_mode = tentacle
tentacle_ip = 127.0.0.1
tentacle_port = 41121
tentacle_opts = 
data_dir = /var/spool/pandora/data_in
allow_regexp = .*
deny_regexp =

As we had configured the file with the values corresponding to our environment, we can deploy the files to the Pandora FMS agent by using file collections. It is a good practice to test the execution before deploy the plugin for first time.

Plugin execution configuration (agent configuration file):

module_plugin /path/to/plugin/pandora_tomcat --conf  /path/to/file/pandora_tomcat.conf

Binary files are also deployed for Windows Pandora FMS agents (pandora_tomcat_x86.exe and
pandora_tomcat_x64.exe)

module_plugin <ruta-plugin>/pandora_tomcat_x86.exe --conf <ruta-conf>/pandora_tomcat.conf
