New functionality is rolling out in Sematext Monitoring!  We just added HAProxy monitoring support for this popular TCP/HTTP load balancer and proxy.

HAProxy Metrics

Sematext collects key HAProxy metrics from the HAProxy load balancer of the underlying proxies/servers, as you can see in the chart below.

Metric Description

downtime total downtime (in seconds)
rate number of sessions per second over last elapsed second
rate_max max number of new sessions per second
rate_lim limit on new sessions per second

bck server is backup (server), number of backup servers (backend)

HAProxy Alerting

You can create threshold-based or machine learning-based anomaly detection on any of these HAProxy metrics, of course, and you can also rely on heartbeat alerts to detect any HAProxy daemon going down.  Any alerts can be emailed or you can use any of the Alert notification integrations such as PagerDuty, Big Panda, Slack, Nagios, or any other WebHook.

See for Yourself

You can check out Sematext live demo and see some more of Sematext monitoring, alerting and anomaly detection functionality.  In addition to native monitoring for apps like Solr, Elasticsearch, Hadoop, HBase, Spark, Cassandra, Kafka, Storm, and many more, Sematext Monitoring also integrates with Sematexts Logs to add centralized logging functionality and correlation of metrics, logs, alerts, anomalies, and events.
