An alert is dispatched when specific text content or HTML nodes appear on or disappear from a public web page. Checks are done at customisable regular intervals.
For example, know when a desired item appears on the sales pages of an online retailer, or when a "discount" label appears on a specific item, or the text "out of stock" disappears from an item.
An alert is dispatched when a specific public web page is inaccessible, or it takes longer than a certain number of seconds to respond. Checks are done at customisable regular intervals.
For example, know when your web site is down or when it is slow to respond.
An alert is dispatched when a ping is received. In other words, the decision that an alert must be dispatched is made external to our service.
For example, at your command, you want an alert to be sent to email, Twilio, Telegram, Discord, Microsoft Teams, and Slack. Send one ping. Done.
An alert is sent at a specific date and time. The alert can optionally be automatically repeated at set intervals.
For example, send an automated SMS or email on a birthday or other special event.
At least one ping is expected within a specified elapsed period. An alert is dispatched if a ping is not received within the elapsed period.
For example, a long-running background job of your application sends a ping every 30 minutes to confirm that it is still functioning normally. We alert you if it does not send a ping within 30 minutes of the last ping.
A measured monitor measures the duration of a task. The clock is started by a start ping and ended by a stop ping. An alert is dispatched if the task took shorter or longer than expected.
For example, send a start ping when a job starts and an end ping when the job finishes. We alert you of any duration anomalies.
Pings are expected at regular intervals, starting from a specific date and time. An alert is dispatched if a ping is not received at the expected time.
For example, a background job of your application must run once every six hours. We alert you if it did not run at the expected time.
Similar to Regular Interval monitors, but the last ping specifies when the next ping must be expected. An alert is dispatched if a ping is not received at the expected time.
For example, a background job of your application dynamically decides when it must run next. We alert you if it did not run at the expected time.
We support more than 60 different SMS, chat, push, webhook, and email services where you can receive alerts.
For example, Twilio, Telegram, Slack, and many more. Scroll down for a full list.
