  • 1.  Devices with robots changing host servers

    Posted May 13, 2019 10:43 AM

    Hi All,

    We need some guidance please.  We are in a situation where we are migrating some of older 2008 servers to 2016 do to the  Microsoft mandates.  We have already encountered some issues with the UIM monitoring being disrupted and data not appearing in the USM console.  BTW all these devices are VM's.

    Case 1  In the most recent case a 2008 device was migrated to a 2016 device. The 2016 device had a different IP than the one it was to replace, and a robot was installed as part of a template so it was running from the start. They took the old 2008 server offline, took its name and IP address and and placed it on the new 2016 server, replacing the original IP and name. The device name appears in the USM console, but it says no metrics when you select it.  The data is there if you go in to report designer, a first there was two device names, one uppercase and one lowercase. Neither had FQDN. We went into SLM, database status and removed any objects associated with the name that only had one metric. Leaving just the one name. We then deactivated and activated the data engine. The problem still prevails. No metrics in the USM.  How can we fix this? and How can we prevent this from happening in the future?

     

    Case 2    We are about to do a similar thing where the 2008 server will be taken offline and decommed and replaced with a 2016 server.  This time however the name of the new server will keep its new name, but we will be taking the IP of the old server and placing it on the new server.  What can we expect from this?  What can we do to avoid the reporting issues mentioned above?

     

     

    All input appreciated

    Thank You

    What is the UIM revision?

    1 run a discovery of the device and then give it some time to see if it correlates.

    2 delete the robot via IM console and then the device via USM and let it get added back after the change is done.

    UIM is 8.5.1 sp1. Not sure what you mean by discovery?

    8.51 with SP1, that's good since it has important updates for discovery.

    usm > Actions > Discovery Wizard

    which results in discovery_agent doing the discovery, passing the info on to discovery_server, discovery_server updates and compares new with existing data to correlate instances of the device. Depending upon what data is there, it gets correlated into one device or not. This KB provides insight as to how it works:

    You may want to try.

     

    1. Run controller callback "_reset_device_id_and_restart" for every UIM robot devices.

    2. deactivate data_engine probe.

    3. NULL clear "ci_metric_id" column in S_QOS_DATA table.

    SQL> update update s_qos_data set ci_metric_id = NULL

    4. activate_data_engine probe.

    5. deactivate discovery_server probe.

    6. activate discovery_server probe.
