Drop-in metrics collection and dashboards for Apache Cassandra
At present, when Cassandra produces metrics, they are added to MCAC via a push model. MCAC then writes the metrics out into files for consumption by collectd. This leaves MCAC...
Collectd acts as a metrics resevoir and serves metrics to Prometheus via json on an exposed port. The number of metrics stored in collectd appears to be governed by two...
There are various places where data is handed off between system components. These include: 1. Metrics being pushed into collectd's netty channel. 2. The netty channel writing out files onto...
Hi, I would like to ask for support for the following issue we are suffering in which we are loosing the metrics collector in our Prometheus instance. **Prometheus scrapping.** ```...
The timestamp in the metrics is 2 hours behind the system time. ``` HELP collectd_collectd_cache_size write_prometheus plugin: 'collectd' Type: 'cache_size', Dstype: 'gauge', Dsname: 'value' # TYPE collectd_collectd_cache_size gauge collectd_collectd_cache_size{collectd="cache",instance="10.0.1.1",cluster="CassCluster",dc="DAL",rack="rack1"} 11969...
When using MCAC's ServiceMonitor configuration I'm observing a lot of metrics popping up of the form collectd_mcac_micros_bucket_RANDOM_DIGITS. I'm curious what these are, and whether they correspond to any meaningful metrics?...
The provided Grafana dashboard embeds https://cassandra.apache.org/img/cassandra_logo.png which may move at any time (this has happened at least once already). It should probably just be removed entirely—it's a privacy concern to...
When running mcac in a test environment with multiple Cassandra nodes per system there is no way currently to define the IP address that the write_prometheus plugin uses to bind...
It is a draft to get things off my head. I think PR #70 should be considered first This naively uses the DataStax documentation as specification: https://docs.datastax.com/en/landing_page/doc/landing_page/metricsandalerts.html And has not...
With the defaults that we have in place, I think no metrics are being filtered away and collectd gets fresh data every 30s. At that point an idle Cassandra 3.11.7...
