using snmp process monitoring for health monitor of smtpd

On the mail server system I added to /etc/snmp/snmpd.conf

 

proc smtpd 150 1

 

snmp will give an error string if there are more then 150 or fewer the 1 process running.

 

 

Using snmpwalk I found the MIB snmpwalk -v2c -c public localhost prTable

 

UCD-SNMP-MIB::prNames.1 = STRING: smtpd

 

UCD-SNMP-MIB::prCount.1 = INTEGER: 0

 

UCD-SNMP-MIB::prErrMessage.1 = STRING: Too few smtpd running ( = 0)

 

UCD-SNMP-MIB::prNames.2 = STRING: pmx-milter

 

UCD-SNMP-MIB::prCount.2 = INTEGER: 0

 

UCD-SNMP-MIB::prErrMessage.2 = STRING: Too few pmx-milter running ( = 0)

 

 

So I could use either snmpwalk or snmpget to retrieve the prErrMessage and act upon that.
