We’ve spoken in the past about Hyperic monitoring, and the roll out of this application to our managed customers. I felt that Hyperic is so slick it deserved more lip service. Some of our customers have already been given access to our monitoring system, and from the feedback we’ve received it would appear they’re quite ecstatic with it. That’s not to say that there aren’t some kinks, because there are, but I must say the microscopic kinks are almost unnoticeable. Hyperic is always improving though, and we’re doing our best to exploit the very best of this application to better serve your infrastructure here at Contegix. The servers that have Hyperic configured on them have a wide range of monitoring options such as:

• CPU Monitoring
• Load Averages
• Filesystem Usage
• Database Monitoring (MySQL, PostgreSQL, EnterpriseDB, etc)
• HTTP Checks
• Zimbra 4.X
• IMAP, POP3, SMTP (on any obscure ports imaginable!)
• Memcached
• Tomcat
• Resin
• Apache HTTP
• And so many more options you would die reading the list

We receive well over a thousand emails a day from our monitoring system, letting us know when your servers are leaving the realm of acceptable levels in a wide variety of categories. This allows us to be proactive in regards to your server’s health, and attack trouble areas before services are impacted. For instance, if we see the load on your server climbing above the typically acceptable level of 5, and staying high, we know to investigate the server before services are impacted.

Most importantly though, you don’t have to deal with the awkward situation of your website’s visitors telling you your site is down, if you’re monitored by our system. If Hyperic is monitoring your site, then that site will be checked every 5 minutes, making sure it gets a response, and checking the site for a search string that should appear on your site. If the monitor fails, we’re alerted immediately, and respond to the situation. If you have special instructions for us, we make every effort to follow them to a tee, and if you don’t have special instructions we’ll handle the situation the best way we know how to return your site to working order. For instance, on typical Java applications, we’ll thread dump the instance, restart it, and notify you of the maintenance that was performed.

I do admit though, as much as we strive to be, we’re not always perfect. At times we do require assistance from you and your team to help us be the best that we can be. While many servers at Contegix follow the Contegix way of doing things, not everything follows exactly what we’re accustomed to. That’s okay though, we don’t mind it, after all these are your servers! However, for us to fully monitor your services to our fullest potential, we do encourage you to let us know what needs to be monitored. Even if you don’t have a special setup, we don’t mind you checking with us on what’s being monitored. In fact, I encourage that too! We want you to feel comfortable here, and if double checking with us that everything you need monitored, is monitored, then drop us a line. There’s absolutely no harm in that, as it ensures that nothing is missed, and that we’re serving you to the best of our ability. Please keep in mind though that running the Hyperic agent on your server will require a small amount of memory, as this is a Java application which means it requires some resources. If you already have a heavily taxed server, throwing the Hyperic agent into the mix may not be a good idea, but I believe this to be a very rare situation.

Finally, maybe the coolest part of Hyperic is that we can give you access to the system as well! This gives you the ability to see the metrics that are produced by the monitoring system for your servers. The access that is granted to you is read only access, so you can’t create sensors, but you can always ask for new ones (again, it’s encouraged!). This ability has already helped a few of our customers, by giving them insight into how their services were behaving, allowing them to clean up trouble spots in their applications and infrastructure. All you need to gain access is drop a line to support@contegix.com, and we’ll be happy to get it setup for you. Let’s take a look at Atlassian for a perfect use-case scenario in which Hyperic can be of great assistance.

Their documentation has a section for monitoring critical production systems. If you visit that section you’ll notice the power of Hyperic on display in the images shown. They go onto demonstrate in that article one particular scenario how the graphs enabled them to catch a critical issue with an instance of theirs, which gave them the nudge in the right direction towards correcting the problem. Furthermore, Hyperic themselves noticed Atlassian’s documentation, and hint at a potential pair of plugins for monitoring Confluence and JIRA in particular! Just remember, we’re here to help you improve in anyway possible. Drop us a line, and get more from your hosting environment with us with Hyperic access!
