This article describes the processes involved in the alarm infrastructure on the CPM and possible causes for the message "Unable to communicate with alarm infrastructure".
Commands accessing the alarm infrastructure report following message: Unable to communicate with alarm infrastructure at this time...
This message is shown directly in the CLI using the following command: show alarms active
At the same time, the messages file may contain the following message: cbshmonitord: [E] Unable to get alarm stats from alarm manager
The above messages may be caused by one of daemons not running or working properly. It may also be related to the situation documented in Knowledge Base article
6044 "WARNING: database "running-config_alt" must be vacuumed". If the latter is the cause, the database must be vacuumed first.
The following processes are used for alarm reporting:
cbsalarmmgrd cbsactivemqd cbshshimd
Status of these processes is monitored by the cbsinitd process. If the cbsinitd process discovers that one of monitored processes is not running, it will kill all remaining running pids for that process and start a new one. This is recorded in the messages file and reported in the following entries:
Aug 2 06:51:02 conwell cbsinitd: [W] [conwell 18.104.22.168] daemon 'daemon.cbsalarmmgrd' pid '1106' not running (3:No such process) Aug 2 06:51:02 conwell cbsinitd: [I] [conwell 22.214.171.124] killing any remaining running pids for daemon 'daemon.cbsalarmmgrd' (prcnam:cbsalarmmgrd) Aug 2 06:51:04 conwell cbsinitd: [I] [conwell 126.96.36.199] starting daemon 'daemon.cbsalarmmgrd' using command '/etc/rc.d/init.d/cbsalarmmgrd start' Aug 2 06:51:06 conwell cbshmonitord: [E] [conwell 188.8.131.52] Unable to get alarm stats from alarm manager Aug 2 06:51:06 conwell cbsinitd: [I] [conwell 184.108.40.206] daemon 'daemon.cbsalarmmgrd' (prcnam:cbsalarmmgrd) is running with 1 pid(s) Aug 2 06:51:11 conwell cbshmonitord: [E] [conwell 220.127.116.11] Unable to get alarm stats from alarm manager
Stopping any of the above mentioned processes will trigger cbsinitd to restart that process. All alarm reporting is reset, and the error message "Unable to communicate with alarm infrastructure" should not be reported anymore.
