Discover the benefits of regularly checking your website's performance and how easy it is to get started.
Website monitoring means that you regularly test your website and verify that it is up and running. A monitoring tool also checks whether visitors can use your website without difficulty. If a problem is detected, you receive an alert.
Uptime is the official term for the time your website was up and running without interruption. It is the opposite of 'downtime', which is the time your website was not working or loading as expected. Read here why uptime is so important.
You might have seen this message before: “Your connection is not private. Attackers might be trying to steal your information.” A monitor will warn you of those HTTPS issues so that you can fix them. This way, your visitors will never get scared away by the above message.
Nothing is more annoying than clicking a link that doesn't work. A website monitor like Semonto regularly clicks every link on your website and notifies you immediately of any broken links so you can fix them.
Mixed content occurs when your initial HTML code is loaded over a secure HTTPS connection, while other resources (such as images, videos, stylesheets, scripts) are loaded over an insecure HTTP connection. In short, mixed content degrades the security of your site.
We also have more advanced monitoring options intended for web developers, server owners and other people who would like to create a custom environment for testing. For more information about those features, consult the sections about Pulse Checks and Server Monitoring in our how-to library.
In Semonto, you can monitor multiple websites at the same time. This is extremely useful for web developers or web agencies who want to make sure that the websites they have created for their customers are still up and running. To add an additional monitor, click ‘create monitor’ at the top right of your screen.
Semonto will check your website every five minutes. (You can change the frequency in the settings up to every minute). If anything requires your attention, you will receive an e-mail on the address that you have used to create your account:
The e-mail will already contain a summary of the issue that has been detected. You can log into Semonto to get more details. You can also choose other ways to get notified. Check our how-to on notifications to activate other ways to get notified.
When you log into Semonto, you will be taken to the status overview.
You can interpret the results by colour:
You can go deeper into the results by clicking the warning. The details will depend on the type of issue.
You can also consult your uptime report which tells you your monthly uptime percentage and the days on which problems were detected.
If you want to know how long a specific incident lasted or what the exact error message was, you can look it up in the incident overview.
You can consult the reachability test results per hour, day, month or year.
When you go to “Websites” and click a URL, you get a menu with all its tests and settings. You can also download a PDF report or delete the monitor altogether.
In the reachability section, you can configure your reachability tests. Don’t worry if the list looks intimidating Semonto works just fine with the default settings, so you are not required to change anything.
This is what you can configure:
There are times when you do not want your monitor to perform any tests. For example, you do not want notifications to go out during planned maintenance. In that case, you can temporarily pause the monitoring. Just go to Websites, click on the website in question and flip the enable/disable switch in the Settings tab. Do not forget to switch it back afterwards.
If you want to continue monitoring but want to turn off notifications for a certain period of time, go to Notifications and turn off the “Notifications are enabled”-switch.
In this section, you find the status and validity of your TLS/SSL certificate. (Read more about TLS/SSL certificate monitoring on our website.) You can consult the entire validation chain, find out who issued the certificate and check the next renewal date. In the settings, you can choose how you want to be notified and configure how many days before the expiration date you want to receive a reminder.
Not sure what broken links are? Then read this first. In the broken links settings, you can enable or disable the monitoring of broken links. You can also adjust your notification settings or tell Semonto to ignore certain links on the website when scanning for broken links.
Read this if you have no idea what mixed content is. In the mixed content settings, you can enable or disable mixed content monitoring. You can also adjust your notification settings or tell Semonto to ignore certain sources on the website when scanning for mixed content.
Content tests tell you whether certain words or phrases are either present on your website (forbidden content) or missing (required content), which could indicate that something is wrong. For example, sometimes websites display ‘will be back soon’ when they are offline. If you enter this phrase as forbidden content, you will receive an alert immediately when it appears. Read more about content tests on our blog.
Sometimes, it can be useful to know the IP-addresses of the Semonto servers. Be sure to allow these IP-addresses in your firewalls, if you are using any. If you use log analyzers, you can filter those IP-addresses to ignore Semonto's hits/requests. Be sure to allow at least all Verification-servers and the TestCenters you use. When we perform a major upgrade, it is possible that another than the preferred TestCenter performs your tests. It is best to allow all our IP-addresses. The IP-addresses can be found in Semonto's dashboard, on the bottom left side of your screen, under the question mark button. And in the following links in multiple formats:
Semonto always gets a ‘second opinion’ before alerting you. If your server is down in one location (for example, Amsterdam) we verify the result by testing again from a second location (for example, New York). Only if both test locations confirm the problem, we send out an alert. This avoids unnecessary notifications of incidents that only lasted a second. If you want, you can go even further and specify how long we should wait before notifying you for each test.
Our current testing locations are:
