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

With more than 30 Kubernetes solutions in the marketplace, it's tempting to think Kubernetes and the vendor ecosystem has solved the problem of operationalizing containers at scale or of automatically managing the elasticity of the underlying infrastructure that these solutions need to be truly scalable. Far from it. There are at least six major pain points that companies experience when they try to deploy and run Kubernetes in their complex environments. In this presentation, the speaker will detail these pain points and explain how cloud can address them.
In an era of historic innovation fueled by unprecedented access to data and technology, the low cost and risk of entering new markets has leveled the playing field for business. Today, any ambitious innovator can easily introduce a new application or product that can reinvent business models and transform the client experience. In their Day 2 Keynote at 19th Cloud Expo, Mercer Rowe, IBM Vice President of Strategic Alliances, and Raejeanne Skillern, Intel Vice President of Data Center Group and GM, discussed how clients in this new era of innovation can apply data, technology, plus human ingenuity to springboard to advance new business value and opportunities.
Discussions of cloud computing have evolved in recent years from a focus on specific types of cloud, to a world of hybrid cloud, and to a world dominated by the APIs that make today's multi-cloud environments and hybrid clouds possible. In this Power Panel at 17th Cloud Expo, moderated by Conference Chair Roger Strukhoff, panelists addressed the importance of customers being able to use the specific technologies they need, through environments and ecosystems that expose their APIs to make true change and transformation possible.
The current age of digital transformation means that IT organizations must adapt their toolset to cover all digital experiences, beyond just the end users’. Today’s businesses can no longer focus solely on the digital interactions they manage with employees or customers; they must now contend with non-traditional factors. Whether it's the power of brand to make or break a company, the need to monitor across all locations 24/7, or the ability to proactively resolve issues, companies must adapt to the new world.
In his session at 20th Cloud Expo, Scott Davis, CTO of Embotics, discussed how automation can provide the dynamic management required to cost-effectively deliver microservices and container solutions at scale. He also discussed how flexible automation is the key to effectively bridging and seamlessly coordinating both IT and developer needs for component orchestration across disparate clouds – an increasingly important requirement at today’s multi-cloud enterprise.
