Troubleshoot Dial Graphs

Consider the following steps to troubleshoot if the dial graphs of the CPU, Memory and Disk Utilization monitors are not displayed.
  1. Go to the device snapshot page and click on the edit icon  that is corresponding to CPU, Memory or Disk Utilization monitors. For example let us conisder that CPU dial is not getting displayed.
  2. Click the Test Monitor button. Test results page opens.

  3. If the monitor did not respond to the test and displays an error message, it is due any of the following reasons.
    • SNMP request to the CPU variable getting timed-out.
    • The OID is not implemented in the MIB.
  4. To confirm the above reasons, invoke the tool MibBrowser.bat [<Probe home>\bin] to verify whether the issue is due to OID not being implemented in the MIB.
    1. Load the Host Resource mib and query the OID .1.3.6.1.2.1.25.3.3.1.2 for the device that is not showing the CPU dial. [For memory the OID is .1.3.6.1.2.1.25.5.1.1.2 and disk is .1.3.6.1.2.1.25.2.3.1.6]. Similarly load the required MIB and query the required OID.
    2. If MIB browser shows response to the query, it implies that the OID is implemented on the device and the issue might be due to SNMP timeout.
    3. Configure the SNMP timeout by including the parameter DATA_COLLECTION_SNMP_TIMEOUT 15 in the file NmsProcessBE.conf [<Probe home>\conf] for the process PROCESS com.adventnet.nms.poll.Collector. Look for the following default entry in this file.

      PROCESS     com.adventnet.nms.poll.Collector
      ARGS  POLL_OBJECTS_IN_MEMORY 25 POLL_JDBC true MAX_OIDS_IN_ONE_POLL 15 AUTHORIZATION true DATA_COLLECTION_QUERY_INTERVAL 120000 PASS_THRO_ALL_POLLING_OBJECTS true CLEAN_DATA_INTERVAL 999999 LOAD_DATA_INTERVAL 60 MAX_ALLOWABLE_INSERT 5000

      Include the mentioned additional parameter. Now the changed entry will be as shown below:

      PROCESS     com.adventnet.nms.poll.Collector
      ARGS  POLL_OBJECTS_IN_MEMORY 25 POLL_JDBC true MAX_OIDS_IN_ONE_POLL 15 AUTHORIZATION true DATA_COLLECTION_QUERY_INTERVAL 120000 PASS_THRO_ALL_POLLING_OBJECTS true CLEAN_DATA_INTERVAL 999999 LOAD_DATA_INTERVAL 60 MAX_ALLOWABLE_INSERT 5000  DATA_COLLECTION_SNMP_TIMEOUT 15
  5. On the other hand if the MIB Browser shows no response, it implies that the OID is not implemented. The vendor must be requested to implement this variable for you. As an alternative you can associate a WMI/CLI based monitor for the device. 
    1. From the device snapshot page remove the SNMP based monitor attached to the device and attach the WMI/Telnet/SSH based.
    2. After associating the WMI/Telnet based monitors, ensure to configure the domain administrator username and password by clicking on the passwords link under the Device Details tab in the device snapshot page.
