While running check_mailq with root user output is as expected but with icinga user it is giving below error:

[root@servername ~]# /icinga/plugins/libexec/check_mailq  -w 1 -c 2
postqueue: warning: Mail system is down -- accessing queue directly
WARNING: postfix mailq is 1 (threshold w = 1)|unsent=1;1;2;0

[root@servername ~]# su - icinga
[icinga@servername ~]$ /icinga/plugins/libexec/check_mailq  -w 1 -c 2
postqueue: fatal: Queue report unavailable - mail system is down
CRITICAL: Error code 69 returned from /usr/bin/mailq

I added icinga user to all below groups

[icinga@servername~]$ groups
icinga root mail smmsp postfix postdrop cgred icinga_cmd

And changed group permission (+rx) for directory and sub-directories under /var/spool/postfix/, /var/spool/clientmqueue/ , /var/spool/mqueue/, /var/spool/snmptt/ & /var/spool/mail/

When I run mailq command with root user it shows mails in queue but with icinga user it just says postqueue: fatal: Queue report unavailable

Please help me to understand if i'm missing anything, why mailq is not giving correct output with icinga user.

Note: I don't want to use sudo.

I have a requirement where check interval is 180 mins while notification interval is 10 mins. Means service owner wants if he miss any alert that usually comes after 180 mins if service is critical then Icinga keeps on checking and informing them every 10 mins until service goes back to normal.

i tried interval = 0 parameter in notification.conf but that is not fulfilling the requirement.

It sends alert every 10 mins if service is not okay but it doesn't check the service.

For eg. if service comes to normal before 180 mins(i.e. next check) , it'll keep on alerting till next check.

Found similar question here but it is for Nagios & i'm not able to merge it with Icinga2.

I'm sure it will be done using CHANGE_NORMAL_SVC_CHECK_INTERVAL parameter but don't know how to implement it.

I also found below Icinga page:

Kindly help.
