Plugins for Monitoring Your WordPress Site's Uptime


Do you know the importance of the uptime of your website? Is your site going down regularly in the middle of the night when those on the other side of the world are trying to visit? Does it take too long to respond so Google's spiders abandon it? Let's look at how you can monitor your website uptime.

What Is Server Uptime Monitoring?

The fact is, users and search engine spiders don't tolerate websites which are broken. They can even punish the site's result rating. To get notified about any error we have to use monitoring solutions. Quick tip: if you have an uptime monitoring tool, you can also use its logs to prove you're right when discussing the service the company promised for hosting (so this can serve as very useful evidence).

"This Site Is Currently Unavailable."


It is wise to think about a couple of questions regarding your WordPress website.

  • Is your website working continuously?
  • How much money are you losing with your webpage business due to downtime?
  • Can you measure when it does work and when it doesn't?
  • What is the reliability or stability of your site?
  • How much traffic can it handle?
  • Do you need to reboot or reset it often?
  • Have you seen your webpage broken ever?
  • Do you get any error messages or a blank (probably white) screen?
  • Maybe empty content with default styling?

In this article we will examine three plugins which can help with this topic.

The Good Old 99% Promise

99% promise

Do you get the usual "99% promise" from your webhosting company? Some providers even go further and offer a 99.9% uptime! Of course some of them won't do as they promised, that is why it's important to choose a good, reliable service. Do some searching and ask some friends and experts about the chosen company. Maybe it is better to consider a more expensive package for example a VPS or dedicated hosting. Also, don't forget about the monthly traffic, which is usually given in gigabytes. Better providers indicate this as well when offering solutions. Some things which appear cheap, actually aren't cheap in the long run.

How Does This Thing Work?

The monitoring servers are checking your website at certain intervals (minutes, hours) and sending messages about the problems if they detected any errors. Some providers allow you to choose the interval for this operation.

Plugin: Pingdom Status

Pingdom is a big service with major users like Microsoft, Ericsson, Amazon, Vodafone and Siemens. To use this plugin you have to have a Pingdom account. This can be a free one, a 30-day-trial one, or a paid version. At Pingdom you can set multiple uptime check frequencies (1 Mins, 5 Mins, 15 Mins, 30 Mins, 60 Mins), and it has good customer service. The company has got a self-developed system for monitoring. This plugin is using the Pingdom API and makes a status page for your WordPress admin.

Pie chart about alerts

It is smart to turn off any error messages on your production WordPress page. You can read a very good, complete tutorial about this technique here at Wptuts+. The article even shows how to turn them into WordPress admin alerts.


Server uptime monitoring lets you quickly know about any errors. Uptime and downtime can be measured and logged. You can also prepare and improve your page using these tools.

    An Introduction To Deploying WordPress with MinaImage400
    As a PHP application, WordPress is usually deployed by a very old method: uploading files via FTP. We have some deployment tools, but they often requires some type of Ruby skill. For example, one popular, powerful tool is Capistrano, but it's also very heavy with many Ruby/Rails related features. I also think that it's little bit tricky to install Capistrano for a PHP developer without any Ruby knowledge. So what options do we have as WordPress developers?

It was truly difficult to pick just five things to talk about, so rather than focusing on the obvious features let's look at some of the less hyped functionality that New Relic provides and how we can use it in interesting and sometimes unorthodox ways. When we left you last time, we had a basic 'Hello World' Rails application (called New Relic_rails1, living in ~/project/tmp/New Relic).
