Hi,
I am running the following snmp packages on a Linux test server under RHEL
Enterprise 4 update 5:
net-snmp-utils-5.1.2-11.EL4.10
net-snmp-devel-5.1.2-11.EL4.10
net-snmp-libs-5.1.2-11.EL4.10
net-snmp-5.1.2-11.EL4.10
net-snmp-perl-5.1.2-11.EL4.10
I am trying to get active monitoring running on my test server. Following
the
man pages, documentation, etc, I thought I would try to get net-snmp to
restart
httpd if it goes down.
When I stop httpd and query the prTable, I see
prIndex.1 = 1
prNames.1 = httpd
prCount.1 = 0
prErrorFlag.1 = 1
prErrMessage.1 = No httpd process running.
prErrFixCmd.1 = /etc/init.d/httpd restart
BUT prErrFix.1 = 0 , which I though should = 1 in this case.
Below is the snmpd.conf that I am using. When I restart snmpd, I see the
following
/etc/snmp/snmpd.conf: line 73: Warning: Unknown token: setEvent.
I am assuming it is because of this error, that prErrFix.1 is not getting
set to 1
and thus httpd is not being restarted.
I am also seeing:
illegal value in mteTriggerBooleanComparison object: -2 repeated 12 times.
I assumed it was because my monitor statements are not correct.
Can anyone shed some light on why net-snmp isn't restarting httpd? What I
did wrong or what I am missing in my snmpd.conf?
Thanks,
Dave
