ArcGIS Enterprise on Kubernetes records events that occur in your deployment, and any errors associated with those events are recorded in the logs. The logs are available in ArcGIS Enterprise Manager.
You can use the logs to monitor and troubleshoot problems with your deployment. Information in the logs can help you identify errors and provide context on how to address problems. Logs also compile a history of events and patterns over time.
Capture, query, and view events
When an event occurs in your site, the event is captured and recorded in the logs. To view messages associated with the event, query the logs. To query and view the current messages in your site, follow these steps:
- Sign in to ArcGIS Enterprise Manager as an administrator.
- Click the Logs button on the sidebar to review the current logs.
Some messages are returned along with additional information.
All logs record several pieces of information regarding the event. You can view and switch columns that display the following:
- Time and date of the log event
- Log level of the event
- Log message
- Source of the log event
- Request ID of the log event
- User name associated with event
- Service type on which the event occurred
- Node on which the log event occurred
- Log code pertaining to the event
- Stack trace of the event
You can also filter logs based on time, log level, source, user name, and request ID.
Troubleshoot using logs
If you suspect you have an issue with a service or node, or a user reports a problem, you can reproduce the event, capture the event with the logs, and query the logs to obtain information about the event. Then use the information in the log to resolve the issue caused by the event.
If an issue is suspected or reported, try to reproduce this issue. If you can reproduce it, query the relevant logs and review the messages for information that may help. For example, if a user reports a performance issue with a web service, reproduce their actions and monitor the logs to see what's occurring. You may find an error message that indicates the cause.
If no information is present, increase the logging level. This broadens the range of logs captured and may provide helpful information.
When working with system logs in ArcGIS Enterprise Manager, you may need to increase the logging level to capture and review events.
You can expand the range of logs that are recorded. You can also examine logs related to service creation and startup in which case you can change the log level from the default Warning to Info.
To update the log level in ArcGIS Enterprise Manager, click Settings on the Logs page.
Logged events can vary in detail from the Severe level, which indicates a problem that requires immediate attention, to the Verbose level, which is a detailed, informative message generated through regular use of the server.
The following table describes the log levels:
Serious problems have occurred that require immediate attention. This level only includes Severe messages.
Unable to process request. Service X not found.
Moderate problems have occurred that require attention. This level also includes Severe messages.
Failed to sign in. Invalid username or password specified.
Common administrative messages include information about service creation and startup. This level also includes Severe and Warning messages.
Accessing organization account settings.
Common messages include information such as names of operation requests received. This level also includes Severe, Warning, and Info messages.
Checking for expired items.
Messages provide detail about how the deployment fulfills an operation, such as noting that each layer in a map service was drawn successfully, how fast the layer was drawn, or how long it took to access the layer's source data. This level also includes Severe, Warning, Info, and Fine messages.
Beginning of layer draw: counties.
Messages are designed for developers and support technicians who want a better understanding of the problem when troubleshooting. It's recommended that you do not use this level in a production environment because it may cause a decrease in performance. If you're not troubleshooting an issue, use the Warning level instead.
Cleaning up directories.
Update the log index
To troubleshoot issues related to accessing logs, for example, if new logs are not generating or if existing logs have become unavailable, you can update the log index.
To update the log index in ArcGIS Enterprise Manager, do the following:
- Click Settings on the Logs page.
- On the Log settings page, click Update log index.
