Configuration help:
Monitoring of an individual process or group of processes requires a process query to differentiate them from other system processes. This is achieved using Process Table Query Language, or PTQL, a simple query language for finding processes based based on their attributes.
PTQL Queries must be in the following format:
Class.Attribute.operator=value
Where:
- Class is the name of the Sigar class minus the Proc prefix.
- Attribute is an attribute of the given Class, index into an array or key in a Map class.
- operator is one of the following for String values:
- eq - Equal to value
- ne - Not Equal to value
- ew - Ends with value
- sw - Starts with value
- ct - Contains value (substring)
- re - Regular expression value matches
- operator is one of the following for numeric values:
- eq - Equal to value
- ne - Not Equal to value
- gt - Greater than value
- ge - Greater than or equal value
- lt - Less than value
- le - Less than or equal value
Multiple queries must delimited by a comma.
Examples:
Find JBoss using process name
State.Name.eq=java,Args.*.eq=org.jboss.Main
Find SSHd using a pid file
Pid.PidFile.eq=/var/run/sshd.pid
For more examples see the pdk/lib/.sigar_shellrc file included in the HQ agent distribution and the Sigar PTQL Documentation.
