View and search logs to monitor performance and troubleshoot issues.

This page describes Cloud Observability’s logs tab. You can also explore logs with Cloud Observability’s Unified Query Builder and Unified Query Language.

Access to Cloud Observability Logging is available on request. Reach out to your Account Manager to get started.

Access the logs tab

To access the logs tab, go to Cloud Observability and click Logs in the sidebar.

You can also access the logs tab from many charts in alerts, dashboards, and notebooks. To open the tab and view logs from your chart’s time range, click data in the chart and select Search logs.

Select time ranges

Use the time picker

By default, Cloud Observability shows data from the past 60 minutes. To change the time range, click the time-picker drop-down and:

  • Set relative time ranges in minutes, hours, days, or weeks.
  • Enter custom time ranges.

    The time picker saves custom time ranges and shows them under Recently used.

You can also click the < > controls next to the drop-down to move back and forward in time.

The image below shows how to select time ranges in the chart. To see the number of logs in a bar, hover over that bar.

Click and drag to select time ranges

View live logs

Live tail auto-refreshes the logs tab with incoming logs. Use it to view and troubleshoot logs in near real time.

To use Live tail, click Play next to the time picker. To stop live tailing logs, click Pause.

You can also live tail specific logs. Filter your logs in the Search logs… box or sidebar and click Play.

Search logs

Search body fields

Cloud Observability tokenizes the body field for fast filtering. Use the Search logs… box to explore and filter logs.

For example, if you search eclipse on the three logs below, Cloud Observability returns the first two logs. The results cover only the selected time range, and you must search for the whole word. For this example, searching ecl returns nothing.

The Search logs… box doesn’t cover other fields besides body (for example, user). See the next section for how to explore those fields.

  • "body": "HEAD /eclipse/moon HTTP/2.0", "size": 7749
  • "body": "PUT /user/eclipse HTTP/2.0", "size": 36208
  • "body": "PUT /spacecat HTTP/2.0", "user": eclipse

To clear a search, click x in the Search logs… box.

Filter other fields

Use the sidebar to explore and filter fields other than body.

To filter logs, select the checkbox next to a field value. Cloud Observability displays the field key-value below the Search logs… box and returns the relevant logs. You can select more than one checkbox. To clear a filter, click the x below the Search logs… box.

You can also use the sidebar to do the following:

  • Search field names - Filter the field names in the sidebar.
  • Search field values - Filter field values for the relevant field name.

    The sidebar displays up to 100 field values per field name.

  • Sort - Click Sort to organize field values by frequency or name.
  • Pin - Click the pin icon to move the field to the top of the sidebar and keep it there.
