Typescript library for publishing metrics from Ceramic nodes, as ceramic model instance documents
Publishes metrics about Ceramic Nodes, on the Ceramic Network
Uses the decentralized CeramicNetwork to publish metrics and data about Ceramic Nodes
In your daemon.config.json
file (often found in ~/.ceramic directory), add the following setting:
"metrics": {
"metrics-publisher-enabled": true
}
and restart your ceramic daemon.
Since the code to record metrics will already be incorporated into the daemon, no further action is necessary.
Note, this class will be included as a dependency in ceramic daemon, so installation is not necessary.
However, if using in your own project, the package can be installed normally.
npm install @ceramicnetwork/node-metrics
Import the class, start the metrics publishing service and record metrics.
import { NodeMetrics, Counter, Observable } from '@ceramicnetwork/node-metrics'
NodeMetrics.start({ceramic: ceramic, network: 'dev-unstable', intervalMS: 30000})
NodeMetrics.observe(Observable.TOTAL_PINNED_STREAMS, 100)
NodeMetrics.count(Counter.RECENT_COMPLETED_REQUESTS, 20)
ModelMetris.recordError('oops')
NodeMetrics.stopPublishing()
If wishing to modify the metrics model, start by updating the model definition in the ./composites
directory, then
composedb composite:create your-schema.graphql --output=../__generated__/definition.json --did-private-key=your-private-key
cd ../__generated__
composedb composite:deploy definition.json --ceramic-url=http://localhost:7007 --did-private-key=...
composedb composite:compile definition.json definition.js
Depending on the changes made, code changes may need to be made as well, in particular start with the list of models defined in src/publishMetrics.ts
