Monitor Configuration GUI Message Source Configuration: Monitoring Values
Monitor Types • Program • Script/program distributed and scheduled by VPO • MIB Object • Object ID of a MIB instance to be checked • External • Script/program scheduled externally Message Source Configuration: Monitoring Values
Monitor Conditions This area layout is unique to Threshold Monitor Conditions Message Source Configuration: Monitoring Values
Message Generation Policy Threshold Reset time [min] Message Generation with RESET 3 min 3 min Message Generation without RESET 3 min 3 min 3 min Continuous Message Generation 3 min 3 min 3 min Message Source Configuration: Monitoring Values
1 1 2 2 3 3 4 4 5 5 6 6 time [min] time [min] Program/MIB Monitoring with Duration Specification External Monitoring (opcmon) Internal Monitoring (Scripts) Threshold Threshold Reset Reset 3 min 3 min Message Source Configuration: Monitoring Values
Monitoring Command Interface Command Syntax to submit monitored values: opcmon <parameterlist> Parameter Value Required monitor_name= name of monitor to deliver value to yes object= component which caused/detected noor was affected by the problem -option <var>= additional parameter of any kind nosupplying a value; may be given multiple times Message Source Configuration: Monitoring Values
Customer Specific Scripts #!/usr/bin/sh # set path to prevent trojan horses PATH=/usr/bin:/opt/OV/bin/OpC # determine the number of running processes value=`ps -e|grep -v grep|wc -l` # forward the value to the VPO monitor agent opcmon ExampleMonTmpl=$value exit $? # return status to the monitor agent Message Source Configuration: Monitoring Values
Identification of data value Monitor name Object Multiple monitor conditions Pattern match for object Threshold check for data value Duration check Set attributes Severity, Node, Application, Message Group, Object, Message Text Example: Control usage of multiple disks with one monitor Object Monitoring multi_disk_util /usr /opt /var Message Source Configuration: Monitoring Values
Distributing Threshold Monitors VPO will identify which nodes require the update Select Templatesand Monitors Message Source Configuration: Monitoring Values

Example 4 - opcmon using -object • opcmon disk_util=91 -object / matches condition ?? • opcmon disk_util=77 -object /disk1 matches condition ?? • opcmon disk_util=75 -object /var matches condition ?? • opcmon disk_util=91 -object /usr matches condition ??

Example 5 - opcmon -object -option • opcmon disk_util=91 -object / -option device=/dev/dsk/c0t6d0 Message Source Configuration: Monitoring Values
