SNMP DCA monitor reject delayed responses with ICMP unreachable result. Within the threshold of configured timeout and retry, in the event of an ICMP unreachable, the monitor marks the weight to the default (1).
Delayed SNMP responses are rejected by the monitor.
Configure a pool_member with SNMP_DCA monitor. Delay the SNMP server's response.
Write an external monitor script, using the snmpget utility. For example: ------------ # values provided by bigd node_ip=`echo $1 | sed 's/::ffff://'` # example: use snmp get command=$(snmpget -v 2c -c private '$node_ip' -r 3 -t 5 .1.3.6.1.4.1.2021.4.5.0 .1.3.6.1.4.1.2021.4.6.0 .1.3.6.1.4.1.2021.11.50.0 .1.3.6.1.4.1.2021.11.51.0 .1.3.6.1.4.1.2021.11.52.0 .1.3.6.1.4.1.2021.11.53.0 .1.3.6.1.4.1.2021.9.1.2 .1.3.6.1.4.1.2021.9.1.9) To configure an external monitor: --------------------------------- -- tmsh create sys file external-monitor my_snmp_exec source-path file:/config/monitors/my_snmp2.sh. -- tmsh create ltm monitor external my_snmp run my_snmp_exec. -- tmsh create ltm node nodeA address 1.1.1.1 monitor my_snmp.
