can't read "splunkdestinationip_withrd": no such variable

[suarezry]

We are running Splunk v7.2.1 on-premise with F5 LTM v11.5.4. We are seeing some F5 events in splunk (source=bigip.snmptrap and source=bigip.syslog) but we suspect that we are missing a great deal more. The following is logged in the F5:/var/log/ltm:

Dec 18 04:20:19 slot1/my-f5-ltm err scriptd[8262]: 014f0013:3: Script (/Common/analytics-iapp_splunk-send_stats1) generated this Tcl error: (script did not successfully complete: (can't read "splunkdestinationip_withrd": no such variable     while executing "string compare "$splunkdestinationip_withrd" "0" "     ("Splunk" arm line 5)     invoked from within "switch -- $format {                 "Splunk" -                 "F5 Analytics" {                     catch {exec /bin/gzip $filename$i$ext -f}         ..."

We do have the correct IP and port listed in "Analytics System Configuration" section and we are seeing some F5 events. Any idea how to fix these errors?

Sorry, this wasn't a splunk issue. I logged a case with F5 and it turned out to be an issue with the iApp. They have released v3.7.2rc5 of the iApp to address this.

@suarezry : did you look at this f5 article related to that error...

This error is related to iApp running on F5 LTM.
Would it be this one?

Try to check on F5 site.
I assume that there is missing configuration, which didn't populate splunkdestinationip_withrd variable.
