After you login to your account at UptimeRobot.com, click on the “+ Add New Monitor” on the left side.

You can choose from multiple options of monitor types:

• HTTP(s)
• Keyword
• Ping
• Port
• Heartbeat

Creating a monitor is as simple as adding a URL or IP address.

For the Keyword Monitor you need to add a specific keyword that should be (or not) present on your website. Set the “Alert When” option to “Keyword Exists” to be notified when, for example, keyword “Error” is present.

You can also choose the “Keyword Not Exists” option and enter a keyword available on your website when it’s online and functional.

For the Ping Monitor you need only the correct IP (or Host). Additionally, for the Port Monitor, you can set a URL and port, too.

For the Heartbeat Monitor enter a Friendly Name and click on “Create Monitor”. After, click on the Settings button and “Edit”. Take a look at the screenshot.

Here you will find the address to which you can send your requests. If we don’t receive one, your heartbeat monitor will become “DOWN”.

How to send regular HTTP requests in Unix/Linux and Windows?

If you are on a Pro Plan, you will have Optional Advanced Settings available for your HTTP and Keyword Monitors:

HTTP Method:

Choose from HEAD, GET or POST (GET or POST for Keyword Monitor) or PUT, PATCH, DELETE, or OPTIONS.

Authentication Settings:

HTTP Basic or Digest Authentication Types are available.

Custom HTTP(s) Statuses:

Edit your UP and DOWN status codes as you wish.

Custom Headers:

Add multiple Custom Headers - their Name and Value.

SSL Settings:

Here you can ignore SSL errors or Disable SSL expiry reminders.

It works in an opposite way compared to other monitoring types. Heartbeat Monitor is the best solution to monitor endpoints inside an intranet (but connected to the internet). It's also suitable for regular/cron jobs your website/app may be performing.

We will provide a unique URL for each heartbeat monitor to which your device/server/computer will be sending requests. Once it doesn't arrive, you will receive a downtime alert.

There could be more reasons for it. You should be able to find details like timestamp and reason along with duration in your Dashboard under each monitor.

If the monitor is grey and showing “No Data”...

...after an hour since you created it, please, contact our support team.

If the monitor is down and you didn’t receive any notifications...

...please make sure your alert contact is attached to the monitor. Click on the Settings button next to your monitor on the left side and then “edit”.

Here on the right side you can find all your alert contacts where you can add them.

Firstly, please, make sure all our IPs are allow-listed on your end and by your provider. They can be all found here.

If there are still any issues, you can try removing the monitor and creating it again. This will change the IP address of your monitor.

If there’s a “Connection Timeout”, take a look at the Response Times graph and see if there are some longer responses. The monitor will be marked as down after 45 seconds of not being able to reach your URL.

My glitch.me/com, Heroku, or similar monitor is not working Glitch.me, for example, is preventing ping services from reaching their servers and keeping their apps awake.

You can find more details here.

The user agent we use is: Mozilla/5.0+(compatible; UptimeRobot/2.0; http://www.uptimerobot.com/)|

Yes, you can use our cachebuster feature, please take a look at this article.

The “Bulk Actions” feature is a bit hidden, true (we're already working on a redesign, don’t worry). You can pause, start, reset or delete your monitors, change intervals, alert contacts and SSL settings, or add a maintenance window.

You can also change the notification settings for your attached alert contacts to be notified every “xy minutes if down for xy minutes”. This is a Pro Plan feature.

The monitor is still active when it’s down and checking if the service is back up.

To get a full list of our IPs, please, follow this article.

In some special cases you have to give an access to the monitored location manually. It depends on server or software you are using. If you need to allow-list UptimeRobot, here are the IPs.

Here are short details about monitor types:

• http(s): it's perfect for website monitoring. The service regularly sends requests (which are the same as if a visitor is browsing your website) to the URL and decides if it is up or down depending on the HTTP statuses returned from the website (200-success, 404-not found, etc.)
• ping: this is good for monitoring a server. Ping (ICMP) requests are sent and up/down status is decided according to the "if responses are received or not". Ping is not a good fit for monitoring websites as a website (its IP) can respond to ping requests while it is down (which means that the site is down but the server hosting the site is up)
• port: good for monitoring services like SMTP, DNS, POP as all these services run from a specific port and UptimeRobot decides their statuses if they respond to the requests or not
• keyword: checks if a keyword exists or not exists in a web page
• cron-job (heartbeat): good for servers/computers/devices that are inside an intranet (but connected to the Internet) and need to be monitored. The feature works in the opposite way compared to other monitoring types. UptimeRobot provides a unique URL for each heartbeat monitor created and expects the monitored item to send regular requests to this URL. Once a regular request doesn’t arrive on time, the monitor is marked as down

The limit for the file size is 8 MB. If it’s bigger, we recommend setting the HTTP method to HEAD. You will find it under the “Advanced settings” when editing a monitor.

We’ll let you know if there’s no response in 1 – 60 seconds, according to your settings, so you can improve the very important speed of your website.

Unfortunately, this feature is not available at the moment, but it’s already on the feature requests list.

• UptimeRobot sends HTTP requests every x minutes from its main engine (US-Dallas)
• If no response is received, another request is sent from the same location (in case the previous one was just a hiccup)
• If no response is received again, it sends 2 other requests in parallel from 2 random and remote locations (the list of locations can be found here)
• If these 2 remote requests fail to get a response too, then the monitor is marked as down and notifications are triggered
• Or, if the monitor returns an erroneous HTTP status, it is instantly marked as down without verification (as the status is returned from the monitor itself)
• And, once a monitor is down, UptimeRobot keeps sending requests every 1 min (no matter the default monitor interval) for faster uptime recovery, only from the main location
• So, in case of a 30 min downtime (except HTTP-status-based downtimes), the monitor needs to:
• • fail to respond twice from the main engine
  • fail to respond from 2 remote locations
  • and must have failed to respond at least 20-25 times in a row from the main location (as the requests are sent only from the main location once the monitor is down)

There are some rare/edge scenarios like:

• our requests/IPs may have been temporarily blocked by a firewall
• there may have been a problematic hop between UptimeRobot's servers and monitor's server. And, if all the requests UptimeRobot has sent passed from that problematic hop at some point, the requests may have failed and UptimeRobot would think that the site didn't respond. This is the main reason we send "verification requests" from multiple locations to minimize this risk and it is very very low
• both of these scenarios have a very low possibility, yet, still wanted to share.. just in case

For the Pro Plan, it is possible to:

• get a “DOWN” notification only if the monitor is down for x minutes
• and, optionally, keep getting the “DOWN” notifications every y minutes

Simply, you may configure your settings like “if down for x minutes alert once” or “if down for x minutes, alert every y minutes“. Please check our related blog post for details.

Actually, you can use the Keyword monitor which is available for the Free-Plan as well.

Keyword Monitor is searching for the keyword you entered but that's not all of that, for there is a condition you must select too.

• Keyword Exists
• Keyword Not Exists

Based on the condition you select the Keyword Monitor will decide if the monitor will be “DOWN” or “UP”.

If the condition you selected becomes true, the monitor will show “DOWN” and notify you, if not, the monitor will keep showing “UP” and no alert notification fired.

For example: If you choose the condition Keyword Exists then the monitor will turn “DOWN” if it finds the Keyword on the page and will notify you.

Unfortunately, if you clicked on the “Reset States” all logs for this monitor will be erased and there is no way to return them back.

Unfortunately, this feature is not available at the moment.

If your monitor status changed and you didn't receive a notification, make sure you have attached the alert contact to your monitor. Click on the Settings button next to your monitor on the left side and then "edit".

Here on the right side you can find all your alert contacts where you can add them.

In the Pro Plan you can find “advanced options” under your alert contacts and set the notification to be sent after “xy minutes” “if down for xy minutes”. This is a Pro Plan feature.

After you log in to your account, click on your email in the upper right corner and "My Settings".

Click on the “Add Alert Contact” (or "Add Integration") in your and choose Slack Alert Contact Type.

Enter the Friendly Name of your contact and your Slack Webhook URL. You can find the link to where it can be created in the blue windows below. You will be redirected to the app to create the webhook.

Custom value would add a specific text to each notification you receive on Slack.

After you log in to your account, click on your email in the upper right corner and "My Settings".

Click on the “Add Integration” (or "Add Alert Contact") and choose Pagerduty Alert Contact Type.

Enter the Friendly Name of your contact and your Pagerduty URL (Integration Key). To get this from Pagerduty please follow the Generate a New Integration Key instructions.

You will receive a notification 30 days in advance, in case of Let’s Encrypt certificate it’s 3 days before the expiration date.

Public status page is a free feature available for all. Find the option to “Add Public Status Page” in your Dashboard after you log in at UptimeRobot.com.

You can choose if you want to show all or specific monitors, enter the name of your status page, add your own logo or set a custom domain (status.yourwebsite.com). Don’t forget to set the CNAME DNS record to stats.uptimerobot.com in that case.

You can make your status page private, too. Just enter a password.

Note: If you are using Cloudflare and a Custom Domain, take a look at this article.

That's a good question. UptimeRobot is launched in January 2010 and it is totally free since then.

It all started with the desire to create a useful and available tool for the web community. After some time, the service grew so much, we spent lots of hours improving it and learned a lot.

Update 13 Jan 2015: We have introduced a Pro Plan today. And, the Free Plan is still here to stay :)
