Popular website monitoring service Pingdom is closing its free accounts starting January 28, 2016. In this article, we have collected some free alternatives to help you replace Pingdom.
Why monitoring is needed
Monitoring allows you to automatically monitor the health of your site, and receive notifications every time your site does not open – background update failure, packet loss at the network provider, problems with the hosting provider, etc.
Many services allow you to track not only the response from your web server, but also view the content of these responses, check the health and validity of SSL certificates, measure page opening time, and check the operation of additional services on your server.
Jetpack is one of the most popular plugins for WordPress. It has a large number of modules built-in, one of which is Jetpack Monitor. It uses the infrastructure of the WordPress.com network to monitor the health of your site and sends you email notifications if there are any accessibility issues.
This module does not have additional settings and types of checks, does not have the ability to send SMS or Push notifications, etc., but its simplicity is one of the pluses, especially for less experienced website owners.
Yandex.Metrica is an external service for collecting visitor statistics on your site. There are a large number of plugins for inserting the counter code into a WordPress site.
In the counter settings on the Yandex.Metrica service website, you can enable notifications about problems, and there is also the option to receive SMS messages.
Uptime Robot is one of the main competitors of the Pingdom service. They provide almost all the same features as Pingdom, and there are no plans to close the free version of the service.
It is worth noting that the free version does not include SMS notifications, but if you wish, you can purchase a package of SMS messages from $15 for 50 pieces. There are several unofficial plugins for WordPress to integrate with Uptime Robot.
StatusCake has a lot of additional features, but if you only need to monitor the availability of your site, then its free version is fine.
The paid version of StatusCake has the ability to check the content of your pages, scan the front of the site for viruses, check the validity of SSL certificates, monitor your DNS servers, create public status pages, and much more.
Nagios Core is a free utility that you can install on a single server and monitor an unlimited number of sites, services, and more. When problems arise, you can receive an e-mail, push notifications (for example through the free Pushbullet service), SMS messages, or calls, for example through Twilio.
This utility has a plugin system with which you can track additional services and indicators. For example, you can monitor the load on your server, memory consumption, network status. If you are using Memcached for WordPress, you can also monitor the status of the Memcached server.
Nagios Core has a quite convenient (albeit not very beautiful) web interface, but keep in mind that the configuration of this utility requires basic knowledge of Linux, and we recommend that you always install Nagios in a data center separate from the data centers where your sites are located.
