Connect2id

Monitoring

1. Overview

The Connect2id server provides over 100 useful metrics and backend health checks. These are implemented with the Dropwizard Metrics library.

Access to the monitoring endpoint is protected by means of a long-lived token. The token must be passed with each HTTP request in the Authorization header:

Authorization: Bearer ztucZS1ZyFKgh0tUEruUtiSTXhnexmd6

The token can be alternatively passed as an access_token URL query parameter, for example, to enable polling of the healthcheck endpoint from a load balancer / reverse proxy:

https://demo.c2id.com/monitor/v1/healthcheck?access_token=ztucZS1ZyFKgh0tUEruUtiSTXhnexmd6

Security note: Avoid passing the token as a query parameter to prevent the credential from appearing in web server logs.

Note that the available metrics can also be reported to a remote data collection / dashboard server via JMX or the Graphite protocol.

More information can be found in the monitoring configuration reference.

  • timers {object} Timers:

    • [infinispan-cache-name].dynamoDB.getTimer Times DynamoDB get operations.

    • [infinispan-cache-name].dynamoDB.putTimer Times DynamoDB put operations.

    • [infinispan-cache-name].dynamoDB.deleteTimer Times DynamoDB delete operations.

    • [infinispan-cache-name].dynamoDB.processTimer Times DynamoDB process (scan) operations.

4.5 Gauge

A gauge from a metrics set.

  • value {integer} The current gauge value.

4.6 Meter

A meter from a metrics set.

  • count {integer} The number of metered events.

4.9 Health check results

Connect2id server health check results.

  • [infinispan-cache-name].availability {object} A JSON object representing the result of checking the availability of the given Infinispan map / cache. Reports degraded map / cache states due to a “spit brain” condition (in a replicated or distributed cluster).

    • healthy {true|false} Indicates the health.

    • [ message ] {string} Diagnostic message if healthy is false.

    • duration {number} Time it took to perform the check, in milliseconds.

    • timestamp {string} Time when the check was completed.

  • [infinispan-cache-name].sqlStore.pool.ConnectivityCheck {object} A JSON object representing the health of the connection pool when an SQL store is configured. The check obtains a JDBC connection from the pool and immediately returns it.

    • healthy {true|false} Indicates the health.

    • [ message ] {string} Diagnostic message if healthy is false.

    • duration {number} Time it took to perform the check, in milliseconds.

    • timestamp {string} Time when the check was completed.
