HAProxy Monitoring Support By @Sematext | @DevOpsSummit [#DevOps]

HAProxy Monitoring Support

New functionality is rolling out in SPM Performance Monitoring!

Watch this space for future posts on Transaction Tracing, Global and App-specific Server Views, Kafka 0.8.2 monitoring and other cool stuff.

For this post, those of you who use HAProxy are in luck as we just added monitoring support for this popular TCP/HTTP load balancer.

See also: Apache monitoring, and Nginx & Nginx Plus monitoring.

HAProxy Metrics

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

Metric Name Description
status 1 (UP/OPEN) 0 (DOWN)
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
scur current sessions
smax max sessions
slimit sessions limit
stot total sessions
lbtot total number of times a server was selected
bin bytes in
bout bytes out
dreq denied requests
dresp denied responses
ereq error requests
eresp response errors
econ connection errors
wretr retries (warning)
wredis redispatches (warning)
weight server weight (server), total weight (backend)
act server is active (server), number of active servers (backend)
bck server is backup (server), number of backup servers (backend)

You can create threshold-based or machine learning-based anomaly detection on any of these 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 SPM Alerts Integrations such as PagerDuty, HipChat, Slack, Nagios, or any other WebHook.

See for Yourself

You can check out SPM’s live demo and see some more of SPM’s 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, SPM also integrates with with Logsene Log Management and Analytics to add centralized logging functionality and correlation of metrics, logs, alerts, anomalies, and events.

Take a Test Drive — It’s Easy and Free to Get Started

DevOpsSUMMIT at CloudEXPO, to be held June 25-26, 2019 at the Santa Clara Convention Center in Santa Clara, CA – announces that its Call for Papers is open. Born out of proven success in agile development, cloud computing, and process automation, DevOps is a macro trend you cannot afford to miss. From showcase success stories from early adopters and web-scale businesses, DevOps is expanding to organizations of all sizes, including the world's largest enterprises – and delivering real results. Among the proven benefits, DevOps is correlated with 20% faster time-to-market, 22% improvement in quality, and 18% reduction in dev and ops costs, according to research firm Vanson-Bourne. It is changing the way IT works, how businesses interact with customers, and how organizations are buying, building, and delivering software.
The benefits of automated cloud deployments for speed, reliability and security are undeniable. The cornerstone of this approach, immutable deployment, promotes the idea of continuously rolling safe, stable images instead of trying to keep up with managing a fixed pool of virtual or physical machines. In this talk, we'll explore the immutable infrastructure pattern and how to use continuous deployment and continuous integration (CI/CD) process to build and manage server images for any platform. Then we'll show how automate deploying these images quickly and reliability with open DevOps tools like Terraform and Digital Rebar. Not only is this approach fast, it's also more secure and robust for operators. If you are running infrastructure, this talk will change how you think about your job in profound ways.
