We have distributed version of ICINGA. We could see on icingaweb text I get the instance status is this:
Instance 'default' (status is false, data is 420.08 minutes old)
only Services were not getting updated from Jan7.
1) Mysql was not rebooted. I have rebooted mysql which looks good
2) php.ini - No changes to file
; Defines the default timezone used by the date functions
;date.timezone = America/Chicago
Please suggest me any other things to check it
