What is prErrorFlag?

This OID is a 1/0 error flag indicating whether the number of running instances of the monitored process has fallen outside its configured prMin/prMax range. An admin polls this to get a quick pass/fail signal without having to compare the count and bounds manually.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.2021.2.1.100
snmpwalk -v2c -c public <target> UCD-SNMP-MIB::prErrorFlag

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.2021.2.1.100.1
snmpget -v2c -c public <target> UCD-SNMP-MIB::prErrorFlag.1
