check_cdot_metrocluster_check.pl: Can't call method "children_get" on an undefined value

[tectumopticum]

Error-message occured during an power-outage at the site:
Can't call method "children_get" on an undefined value at check_cdot_metrocluster_check.pl line 69.<Terminated with exit code 255 (0xFF).>

Last state before this error:
CRITICAL: lifs: warning
|nodes : ok
lifs : warning
config_replication : ok
aggregates : ok
clusters : ok
connections : ok
volumes : ok

Only while the outage? Has the error message been cleared after power on again?

Hi Alex, yes - after the outage the "undefined value"-error disappeared. During the outage it looks like $status was undefined or its input was not as expected?

Maybe this could help to avoid the irregular termination:

unless (defined $status) {
print "UNKNOWN: 'attributes-list' not found in API-output\n";
exit 3;
}

Currently we also see messages like this every hour:
UNKNOWN: A MetroCluster check operation is in progress. Wait for it to complete and retry this command. To check the status of the running MetroCluster check operation, use the "metrocluster operation history show -job-id 23965".

Best regards!
