Hello,
I recently noticed that I don't have impstats metrics for my rulesets main
queues. Counters are always 0.
So I tested with this configuration snippet :
---
module(load="impstats" interval="1")
ruleset(name="foo" queue.type="LinkedList" queue.size="500000") {
action(type="omfwd" protocol="tcp" target="1.1.1.1")
}
action(type="omfile" file="/tmp/log")
call foo
---
Using this configuration I get these messages in the debug log :
---
7651.521245000:2ba0dabd2b80: foo: is NOT disk-assisted
7651.521250000:2ba0dabd2b80: foo: type 1, enq-only 0, disk assisted 0,
maxFileSz 16777216, lqsize 0, pqsize 0, child 0, full delay 485000, light
delay 350000, deq batch size 1024 starting
7651.521254000:2ba0dabd2b80: foo:Reg: finalizing construction of worker
thread pool

instance data
7651.521290000:2ba0dabd2b80: foo: queue finished initialization
---
And /tmp/log :
---
# tail /tmp/log

I believe "type 1" is a LinkedList. But the ruleset behaves like if it had
a Direct queue :
- Messages are not written to /tmp/log.
- If I add queue.timeoutenqueue="0" to the ruleset, messages are written to
/tmp/log.
I expect that behavior with a Direct queue, not with a LinkedList one.
Is it just an issue with the queue counters reporting, or is it possible
that my ruleset don't have LinkedList queues ? Something else I don't
understand ?
Note: In the logs, it is written 7.2.6, but it is rsyslog branch c7.
Thanks for your help.
Regards,
Philippe
