Opened: May 15, 2019

Severity: 4-Minor

Symptoms

When using BIG-IP link monitors with the mentioned conditions, the system logs MCPD error messages (GTM config sync result from local mcpd: result) in the LTM instead of GTM. # tail /var/log/gtm May 15 11:58:54 gtm1a.test.net err iqsyncer[2684]: 011ae104:3: Gtm config sync result from local mcpd: result { May 15 11:58:54 gtm1a.test.net notice gtmd[15881]: 011a0006:5: hookOnChild: SYNC syncer exited with status == 0.(success) # tail /var/log/ltm May 15 11:58:14 gtm1a.test.net err mcpd[9833]: 0107082c:3: Cannot modify the destination address of monitor /Common/my_bigi_link.

Impact

GTM log is missing MCPD error text, which instead gets logged in LTM log.

Conditions

-- A bigip_link monitor with destination * written in bigip_gtm.conf. -- That monitor is associated with a link. -- The following command is run on one of the sync group peers: tmsh load /sys config gtm-only.
