Upgrading EMP software

AppNeta recommends keeping your Enterprise Monitoring Point (EMP) software up to date to take advantage of the latest features and bug fixes. You will see the warning symbol 50x50_trans.png appear at various places in APM (including the Manage Monitoring Points page) when a monitoring point is no longer running the latest software version. You can configure APM to have a monitoring point upgraded automatically or you can upgrade it manually at any time. Note that the upgrade process can result in a gap of up to 15 minutes of monitoring history.

Configure upgrade automation

APM provides flexibility in scheduling monitoring point software upgrades to conform to your maintenance program. There are three upgrade automation settings:

  • Manual - Upgrades are to be performed manually (no automation).
  • Managed - Upgrades are to be performed automatically when new software is released. This enables you to have the latest software running at all times. The software upgrade schedule is listed on the AppNeta service status page: http://status.appneta.com/.
  • Scheduled - Upgrades are to be performed automatically on a regularly scheduled interval. This enables you to schedule upgrades during your regular network maintenance window. You also have the option of skipping the next upgrade.

To configure monitoring point upgrade automation:

  1. Within APM, navigate to > Manage Monitoring Points.
  2. For the monitoring point you want to configure, select > Upgrade Settings.
  3. From the Upgrade Type drop-down, select the type of upgrade automation you want to use.
    • If you select Scheduled you will need to specify the upgrade schedule (Note: The upgrade schedule is based on the monitoring point time zone).
  4. Click Save.
    • The monitoring point upgrade automation is set.

The Upgrade Settings option is also available in the Bulk Action drop-down. Use this feature to configure upgrade automation on multiple monitoring points at the same time.

Manual upgrade

The upgrade process can be performed manually at any time to any model of monitoring point no matter which of the upgrade automation settings is selected.

To upgrade monitoring point software to the latest release:

  1. Within APM, navigate to > Manage Monitoring Points.
  2. For the monitoring point you want to upgrade, select > Upgrade Now.
  3. Click OK.
    • The monitoring point software is upgraded to the latest release.

The Upgrade Now option is also available in the Bulk Action drop-down. Use this feature to upgrade multiple monitoring points at the same time.

Failed upgrade?

If an upgrade attempt fails, try the following:

  1. Retry the upgrade.
  2. Restart the monitoring point then retry the upgrade.
  3. Physically power the monitoring point off for 10 seconds then back on and retry the upgrade.
  4. Reflash the monitoring point using the latest image.

If you are still unsuccessful, contact AppNeta Support.

Reflashing an EMP - local image

Reflashing an Enterprise Monitoring Point (EMP) (local image) involves rewriting the monitoring point file system with a software image stored on the monitoring point. All configuration information is saved during a reflash. This procedure is typically only required when troubleshooting a problem on the monitoring point.

Reflash using the Admin API

  1. Access the Admin API.
  2. Navigate to Appliance > PUT /appliance/reflash/.
  3. Click Try it out.
  4. Click Execute.
    • The Server response section should show Code “200” to confirm that the reflash instruction was received by the monitoring point.
    • The monitoring point reflashes with the locally stored image. Connectivity to the monitoring point is lost during the reflash procedure.

Reflash using a USB stick

To reflash a monitoring point with the local image using a USB stick:

  1. Download the reflash file.
  2. Copy usb-config.yaml to the root of an empty, FAT32-formatted USB stick.
  3. Edit the file with a text editor.
    1. Set the “reset:” line to reset: false.
      • This preserves the network and APM access configuration.
    2. Save the file.
