When querying in the APM app, you’re simply searching and selecting data from fields in Elasticsearch documents. Queries entered into the query bar are also added as parameters to the URL, so it’s easy to share a specific query or view with others.
You can begin to see some of the transaction fields available for filtering:
Example APM app queriesedit
Exclude response times slower than 2000 ms:
transaction.duration.us > 2000000
Filter by response status code:
context.response.status_code >= 400
Filter by single user ID:
context.user.id : 12
Read the Kibana Query Language Enhancements documentation to learn more about the capabilities of the Kibana query language.
Querying in Discoveredit
It may also be helpful to view your APM data in Discover. Querying documents in Discover works the same way as querying in the APM app, and all of the example APM app queries can also be used in Discover.
Example Discover queryedit
One example where you may want to make use of Discover, is for viewing all transactions for an endpoint, instead of just a sample.
Starting in v7.6, you can view 10 samples per bucket in the APM app, instead of just one.
Use the APM app to find a transaction name and time bucket that you’re interested in learning more about. Then, switch to Discover and make a search:
processor.event: "transaction" AND transaction.name: "<TRANSACTION_NAME_HERE>" and transaction.duration.us > 13000 and transaction.duration.us < 14000`
In this example, we’re interested in viewing all of the
that took between 13 and 14 milliseconds. Here’s what Discover returns:
You can now explore the data until you find a specific transaction that you’re interested in.
Copy that transaction’s
transaction.id, and paste it into the APM app to view the data in the context of the APM app:
