AlmaLinux OS Troubleshooting Information
For better understanding, AlmaLinux OS Upgrade can be divided into 4 parts:
-
Running the precheck utility to ensure the health of the system and detect any upgrade issues. This can be done any time before the upgrade using the standalone precheck-tool rpm. (required only on NW Server)
Logs are recorded in this path - /var/log/netwitness/precheck-tool/checklist.log
-
Initialization or init phase (happens only on NW Server)
For any issues during init phase, check these logs.
-
salt minion logs - /var/log/salt/minion
-
deployment-upgrade logs - /var/log/netwitness/deployment-upgrade/chef-solo.log
Note: Please perform the init only when you plan to do the actual upgrade. It is not recommended to perform an init without upgrading the system in the same change window.

OS Upgrade from CentOS to AlmaLinux
As the first step of OS Upgrade, salt gets upgraded. You can execute the below command to see that salt is upgraded to version 3006:
cat /var/log/yum.log | grep salt
You can view similar to the below update where xxx represents the current datetime stamp:
xxx Updated: salt-master-3006.2-0.x86_64
xxx Updated: salt-api-3006.2-0.x86_64
xxx Updated: salt-minion-3006.2-0.x86_64
For any issues, with salt-upgrade, please check:
-
/var/log/netwitness/node-infra-server/node-infra-server.log
-
/var/log/salt/master
-
/var/log/salt/minion
Once salt has been upgraded, the leapp process will begin.
The logs can be viewed in /var/log/salt/minion:

For any issues encountered during OS Upgrade, the logs below will be helpful in troubleshooting.
-
/var/log/salt/minion
-
If Preupgrade fails - /var/log/leapp/leapp-preupgrade.log
-
If Leapp upgrade fails - /var/log/leapp/leapp-upgrade.log
If leapp fails, then /var/log/leapp/leapp-report.txt will provide you with details about inhibitors.
A few minutes after this log “Running leapp upgrade” in /var/log/salt/minion, the system will reboot and may take 20 to 30 minutes to return.
Once it is up, you can confirm the OS using the command cat /etc/almalinux-release. If it does not show Alma Linux release, please call Customer Support before taking any action.
Also, if you have triggered the upgrade through UI and see the status "Performing OS Migration" on any NodeX for more than an hour, please check the leapp logs and reach out to Customer Support.

| Problem |
You will see the following message in the orchestration-server.log. |
| Cause | Salt minion may have been upgraded and never restarted on failed non-NW Server host |
| Solution |
|
| Problem |
When you install and orchestrate a fresh 12.5.0.0 core Node-X to the Admin server (Node-0) upgraded from 12.0 or older versions to 12.5.0.0, the core services such as Concentrator, Log Decoder, Log Collector, Archiver, Decoder, Appliance, Workbench, Warehouse Connector, and Broker appear inactive under the Services column in the Admin > Hosts view. As a result, you cannot access the core services in the UI. This is not applicable if you are orchestrating a fresh 12.5.0.0 core Node-X to the fresh-Installed 12.5.0.0 Admin Server (not upgraded from 12.0 or older versions to 12.5.0.0). |
| Cause | The 12.5.0.0 core Node-X uses a dedicated SA-server certificate instead of the common Node-0 node certificate under its trustpeers if it is orchestrated directly to an upgraded 12.5.0.0 Admin Server host. |
| Solution |
|

| Solution |
To resolve the issue In the NetWitness user interface,
Note: Do the above procedure for all the configured data sources.
|
Legacy Windows Log Collector
| Problem |
Legacy Windows Log Collector appears as inactive when the stack is upgraded to 12.5.0.0. |
| Cause | Certificate update in the Admin Server node. |
| Solution |
Refer Legacy Windows Log Collector section in the Perform Post Upgrade Tasks. |
ESA Troubleshooting Information
ESA Rules are Not Creating Alerts
If you are not seeing any alerts, check the status of the ESA rule deployments.
- Go to
(CONFIGURE) > Policies > Content > Event Stream Analysis > ESA Deployments.
The ESA Deployment panel is displayed. - Select required deployment from the list and click Deployment Stats tab.
- Deployment Stats page is displayed, which shows the status of your ESA services and deployments.
- For each ESA rule deployment:
- In the Engine Stats section, look at the Events Offered and the Offered Rate. They confirm that the data is being aggregated and analyzed properly. If you see 0 for Events Offered, nothing is coming in for the deployment.
- In the Rule Stats section, look at the Rules Enabled and Rules Disabled. If there are any disabled rules, look in the Deployed Rule Stats section below to view the details of the disabled rules. Disabled rules show a red circle. Enabled rules show a green circle.
- If you notice any disabled rules that should be enabled:
- Go to
(Configure) > ESA Rules > Rules tab and redeploy the ESA rule deployments that contain disabled rules.
- Go back to the Services tab and check to see if the rules are still disabled. If the rules are still disabled, check the ESA Correlation service log files, which are located at /var/log/netwitness/correlation-server/correlation-server.log.
- Go to
Note: To avoid unnecessary processing overhead, the Ignore Case option has been removed from the ESA Rule Builder - Build a Statement dialog for meta keys that do not contain text data values. During the upgrade to latest version, NetWitness Platform does not modify existing rules for the Ignore Case option. If an existing Rule Builder rule has the Ignore Case option selected for a meta key that no longer has the option available, an error occurs if you try to edit the statement and try to save it again without clearing the checkbox.
Example ESA Correlation Server Warning Message for Missing Meta Keys
If you see a warning message in the ESA Correlation server error logs that means there is a difference between the default-multi-valued parameter and multi-valued parameter meta key values, the new Endpoint, UEBA, and Live content rules will not work. Completing the Update the Multi-Valued and Single-Valued Parameter Meta Keys for the latest Endpoint, UEBA, and RSA Live Content Rules procedure in the ESA Configuration Guide should fix the issue.
Multi-Valued Warning Message Example
