'Unclosed compound' error in naemon.log
‘Unclosed compound’ is a catch-all error message found in naemon.log that could mean several configuration issues in your merlin.conf.
Let’s take a real-world example that was reported by a client. See below.
Configuration error found in naemon.log:
[2023-05-08T19:47:58Z] *** Configuration error
[2023-05-08T19:47:58Z] in compound 'poller nl-op5' starting on line 90
[2023-05-08T19:47:58Z] in file '/opt/monitor/op5/merlin/merlin.conf'
[2023-05-08T19:47:58Z] ----
[2023-05-08T19:47:58Z] Unclosed compound (there may be more)
[2023-05-08T19:47:58Z] ----
It says that there’s something erroneous in merlin.conf starting on line 90.
We can inspect the file with line number using the command cat with an option –number.
cat --number /opt/monitor/op5/merlin/merlin.conf
Below is an excerpt from the file and at first glance, there’s nothing wrong with line 90. However, upon further inspection, there seems to be a missing } character to close the settings for poller nl-op5. The } character must be defined after line 100. Once defined, save the file and perform mon restart to reflect the changes.
