Meteor metrics

From version 2.2.0 Meteor-elastic-apm by default comes with meteor-measured.

Meteor-measured sends a lot of useful meteor specific metrics:

Sockets Metrics:

  1. Open sockets: 10 sockets open
  2. Live data sockets: 8 sockets uses livedata

Session Metrics:

  1. Sessions count: 8 meteor sessions

Pub/sub Metrics:

  1. Subscriptions count: 100 subscriptions
  2. Subscriptions count for each publication: testPub: 20 subs, notTestPub: 80 subs
  3. Published documents: 20 docs published
  4. Published documents for each collection: 10 docs of TestCollection published, 10 docs of NotTestCollection published

Observer Metrics:

  1. Number of observers: 20 observers created
  2. Number Observer drivers: Oplog drivers: 10, Polling drivers: 10
  3. Number of documents for each driver: TestCollection published by oplog driver: 10

Meteor-measured uses elastic agent registry and sends metrics data directly to kibana.

How to visualize metrics

  1. Start your app with metrics, wait for some time 2-3 minutes, do something in your app to collect and send metrics. We need to wait while elasticsearch will save and index our metrics.
  2. Go to Kibana -> Management -> Index Patterns -> apm-* You will see a list of all indexed fields, click on Refresh Fields list button, the button is located on top-right corner: index_pattern

Sorry for my amazing drawing skills.

  1. After Refreshing was completed try to find some of the fields which we are sending: sessions.count, sockets.open, sockets.liveData.

  2. Time to Visualize our metrics: Go to Kibana -> Visualize -> Create Visualization.

Select Line chart, index pattern should be apm-*

  1. You need to configure the chart to visualize meteor metric data. Let's draw sessions.count metrics, to do so you should configure chart this way: Y-Axis props:
Aggregation = Max
Field = sessions.count
Custom Label = Sessions

X-Axis props:

Aggregation = Date Histogram
Field = @timestamp
  1. Click on blue "Apply Changes" button.
  2. Configure time range to be: 30 minutes ago. Click on "Refresh"

Repeat steps for every metric field you need, you can combine charts in Dashboard later.

Sample sessions count chart: sessions_count

PS: I am not elastic search, kibana expert, maybe there is easier steps to do the same. If you want to correct something or add useful tips and tricks, I am waiting for your PRs
