Hi Infrastructure Management Community,

As promised I am providing the items used to build the Domain Name Service (DNS) dashboard that was presented during the CA on CA Webcast Featuring CA Unified Infrastructure Management https://communities.ca.com/community/ca-infrastructure-management/blog/2016/02/10/webcast-recap-ca-on-ca-featuring-ca-unified-infrastructure-management-uim.

This is how we do it you should make modifications to the content provided to meet your needs. Hopefully this is helpful.

Provided in the attached zipped file are

  • The dns_response probe configuration file dns_response.cfg
    • For each location we have 2 profiles defined
      • § Checks the response time of the internal DNS server by looking up the name of the DNS server
      • § Checks the response time of a popular external name we use www.google.com
      • § Change the thresholds for alarms as needed. I think ours are a little high
    • You will need to modify the configuration to set the DNS server IP address, the forward name lookup and reverse name lookup
  • Our DNS servers are SNMP based appliances that are monitored by the snmpcollector/pollagent probe, this will most likely not apply to everyone so I am not providing this
  • The lists shown in the dashboard are under the ListViewer folder. These can be easily imported using the List Designer portlet using the Import option which is available on the Open screen. Note that there are host restrictions applied to some of the lists, you will need to modify the filters to match your local configuration.
    • Caching DNS Response.xml we use this to monitor the response of our Internet DNS queries
    • Internal DNS Response.xml we use this to monitor the response of our internal DNS queries against internal DNS servers
    • Internal Appliance Performance.xml we use this to display the metrics collected by the snmpcollector/pollagent for the DNS appliances
  • The performance report is available under the PerformanceReportsDesigner folder. This can be easily imported using the Performance Reports Designer portlet using the Import option which is available on the Open screen. Note that we use filters to create our reports, you will need to modify the filters to match the names/IP addresses used in your environment
    • Internal Appliance Performance.xml
  • I have not included a LAR file for this however once you import the Lists and Performance Reports you can add them to a page in UIM and arrange them to your liking. Remember to use the wrench > Preferences > Select your report> Select your time period (we use last hour) > click Save to pick your report or list after adding the relevant portlet to your page.
