Some times these are false alerts. Can you check your sytem load during that time when you received these allerts(CLOCK_OFFSET, DNS_HOST_RESOLUTON, WEB_METRIC etc). sar -q -f /var/log/sa/sa10 Use above command and modify sa10 with the date you have received alerts. track down the load and check what unusal thing happened on that host during that widow. If you see there is a bump up in the load then Check your system I/O disk utilization to see if the spindles are reaching 100%. If any of the spindles are reaching 100% then the system load is the cluprit here. You may need to increase your thresholds on that perticular host in CM> host>all hosts> select on host name> configurations and look for Host Clock Offset Thresholds or Host DNS Resolution Duration Thresholds. As per the present thresholds when the system experience high load it will pause for a while or send delayed response(response includes health check reports of the host when CM scm-agent is running) to the scm-server. When the SCM-server failed to receive these health check reports within the duration due to the host beeing busy then this will cause the alerts to flood in your inbox.
