This section contains sample configuration file directives for process monitoring. Each example shows how to define an instance of process monitoring and explains the attribute or threshold being monitored.
Example: Monitor Sendmail to Ensure It Is Running
The following example configures the agent to monitor the sendmail daemon on a UNIX email server on the underlying system:
watch process procAlive 'sendmail' 11 0x00000100 60 absolute=4 'Monitor sendmail' '' 'processEntry' 'sendmail' 'procAlive' fatal
Indicates that this entry will occupy row 11 (pmonIndex=11) in the Process Monitor table.
Indicates that the agent should monitor the parent sendmail process if more than one sendmail daemon is present and running.
Indicates that the agent should check the sendmail process every 60 seconds.
Indicates that this entry uses processEntry object class for the object state model. The object class is replaced with default value. Here, '*' is an invalid value.
Indicates that this entry uses sendmail object instance for the object state model. The object instance is replaced with default value. Here, '*' is an invalid value.
Note: '//' and '/' can be used as delimiters to relate an instance to a system: '//hostname/instance'. For local system instances '//./' is always prepended to relate the instance to the local system. '//hostname/*', '//*/instance' and '//*/*' are invalid values.
Indicates that this entry uses procAlive object attribute for the object state model. The attribute is replaced with default value. Here, '*' is an invalid value.
Indicates that this entry uses fatal severity for the object state model.
No action is specified, so the agent will not invoke a command when it sends a trap.
Example: Monitor the Simple TCP/IP Services Process To Ensure It Is Running
The following example configures the agent to monitor the TCPSVCS process that makes up the Simple TCP/IP Services service:
watch process procAlive 'TCPSVCS' 12 0x00000000 30 absolute=4 'Monitor NT TCP services' '' 'processEntry' 'TCPSVCS' 'procAlive' warning
Indicates that this entry will occupy row 12 (pmonIndex=12) in the Process Monitor table.
Indicates that the agent should provide the default process monitoring behavior.
Indicates that the agent should check the TCPSVCS process every 30 seconds.
Indicates that this entry uses processEntry object class for the object state model. The object class is replaced with default value. Here, '*' is an invalid value.
Indicates that this entry uses TCPSVCS object instance for the object state model. The object instance is replaced with default value. Here, '*' is an invalid value.
Note: '//' and '/' can be used as delimiters to relate an instance to a system: '//hostname/instance'. For local system instances '//./' is always prepended to relate the instance to the local system. '//hostname/*', '//*/instance' and '//*/*' are invalid values.
Indicates that this entry uses procAlive object attribute for the object state model. The attribute is replaced with default value. Here, '*' is an invalid value.
Indicates that this entry uses warning severity for the object state model.
No action is specified, so the agent will not invoke a command when it sends a trap.
Note: This example illustrates how to monitor the underlying process that provides the Windows Simple TCP/IP Services service. The following example illustrates how to monitor the Windows service itself instead of its underlying process.
Example: Monitor the Simple TCP/IP Services Service
Both of the following examples configure the agent to monitor the TCPSVCS service itself instead of the underlying process:
watch process procAlive 'Simple TCP/IP Services' 13 0x08000 30 absolute=4 'Monitor NT TCP/IP Services' '' 'processEntry' 'Simple TCP/IP Services' 'procAlive' minor
Indicates that this entry will occupy row 13 (pmonIndex=13) in the Process Monitor table.
Indicates that the agent should monitor the Windows service, instead of the underlying process.
Indicates that the agent should check the Simple TCP/IP Services service every 30 seconds.
Indicates that this entry uses processEntry object class for the object state model. The object class is replaced with default value. Here, '*' is an invalid value.
Indicates that this entry uses Simple TCP/IP Services object instance for the object state model. The object instance is replaced with default value. Here, '*' is an invalid value.
Note: '//' and '/' can be used as delimiters to relate an instance to a system: '//hostname/instance'. For local system instances '//./' is always prepended to relate the instance to the local system. '//hostname/*', '//*/instance' and '//*/*' are invalid values.
Indicates that this entry uses procAlive object attribute for the object state model. The attribute is replaced with default value. Here, '*' is an invalid value.
Indicates that this entry uses minor severity for the object state model.
watch ntservice 'Simple TCP/IP Services' 14 0x0 30 'Monitor NT TCP/IP Services' '' 'processEntry' 'Simple TCP/IP Services' 'procAlive' major
Indicates that this entry will occupy row 14 (pmonIndex=14) in the Process Monitor table.
Indicates that the agent should check the Simple TCP/IP Services service every 30 seconds.
Indicates that this entry uses processEntry object class for the object state model. The object class is replaced with default value. Here, '*' is an invalid value.
Indicates that this entry uses Simple TCP/IP Services object instance for the object state model. The object instance is replaced with default value. Here, '*' is an invalid value.
Note: '//' and '/' can be used as delimiters to relate an instance to a system: '//hostname/instance'. For local system instances '//./' is always prepended to relate the instance to the local system. '//hostname/*', '//*/instance' and '//*/*' are invalid values.
Indicates that this entry uses procAlive object attribute for the object state model. The attribute is replaced with default value. Here, '*' is an invalid value.
Indicates that this entry uses major severity for the object state model.
No action is specified, so the agent will not invoke a command when it sends a trap.
Example: Monitor ypbind To Ensure It Is Running
The following example configures the agent to monitor the UNIX ypbind daemon on the underlying system:
watch process procAlive 'ypbind' 15 0x00000000 60 absolute=4 'Monitor ypbind' '/example/pager.sh' 'processEntry' 'ypbind' 'procAlive' critical
Indicates that this entry will occupy row 15 (pmonIndex=15) in the Process Monitor table.
Indicates that the agent should check the ypbind process every 60 seconds.
Indicates that this entry uses processEntry object class for the object state model. The object class is replaced with default value. Here, '*' is an invalid value.
Indicates that this entry uses ypbind object instance for the object state model. The object instance is replaced with default value. Here, '*' is an invalid value.
Note: '//' and '/' can be used as delimiters to relate an instance to a system: '//hostname/instance'. For local system instances '//./' is always prepended to relate the instance to the local system. '//hostname/*', '//*/instance' and '//*/*' are invalid values.
Indicates that this entry uses procAlive object attribute for the object state model. The attribute is replaced with default value. Here, '*' is an invalid value.
Indicates that this entry uses critical severity for the object state model.
The agent invokes the specified action script /example/pager.sh each time it sends a trap. In this case, it invokes the script each time a processStop or a processStart trap is sent. The script should examine its arguments to determine which trap is being sent and send the appropriate message to the target pager.
Example: Monitor the Size of a Process
The following example configures the agent to monitor the overall size of a particular process:
watch process procSize 'netscape' 20 0x00a02400 60 absolute '>' 35000 'Monitor netscape size' '' 'processEntry' 'netscape' 'procSize' none
Indicates the attribute that the agent is monitoring. It returns the size of text, data, and stack segments of the corresponding process. You can determine if this attribute is leaking memory by monitoring it for a given threshold.
Indicates the name of the process that the agent will monitor.
Indicates that this entry will occupy row 20 (pmonIndex=20) of the Process Monitor table.
Instructs the agent to modify the default Process Monitor table behavior as follows:
Instructs the agent to send processClear traps.
Instructs the agent to send up to 10 consecutive traps and then send no more.
Contains the flag value 10 for use with the directive in this example.
Indicates that this entry uses processEntry object class for the object state model. The object class is replaced with default value. Here, '*' is an invalid value.
Indicates that this entry uses netscape object instance for the object state model. The object instance is replaced with default value. Here, '*' is an invalid value.
Note: '//' and '/' can be used as delimiters to relate an instance to a system: '//hostname/instance'. For local system instances '//./' is always prepended to relate the instance to the local system. '//hostname/*', '//*/instance' and '//*/*' are invalid values.
Indicates that this entry uses procAlive object attribute for the object state model. The attribute is replaced with default value. Here, '*' is an invalid value.
Indicates that this entry uses none severity for the object state model.
Instructs the agent to compare each sampled value to the threshold instead of measuring the difference (delta) between successive samples.
Instructs the agent to compare the sampled procSize attribute against the value 35000 (35,000 KB or 35 MB), and to send a processThreshold trap when that threshold is exceeded.
