If the server your script runs on (or rather the XML file) is unreachable for some reason, this will also count as a “down” on Pingdom’s end, so make sure your script runs on a reliable server with a good Internet connection. And if you decide to create a really elaborate, time-consuming script on your end, you may be best off letting it run separately and just have it continuously update a status page (the XML file) that is accessed by Pingdom. If you get any substantial traffic, you do not want to call the API each time you get a page hit, since this may cause you to hit the request limit faster than expected. In general, whenever you can cache data, do so. If you are building a web page using the Pingdom API, we recommend that you do all API request on the server side. You can create your own scripts or applications with most of the functionality you can find inside the Pingdom control panel. The Pingdom API is a way for you to automate your interaction with the Pingdom system. Since you’re returning a value and a status every time your XML page is accessed (for example once a minute), you will be able to see this data in the graphs in the Pingdom control panel and of course be sent alerts just as with any other Pingdom check. If you have a server that is not accessible to the public Internet but critical to your company’s operations, you can set up a server that is reachable by the public Internet and has access to your internal server to ping the internal server and report that data in a XML-form. In which case, a middle server or process can be used to generate XML data that can be read by Pingdom’s custom check.Īnd what if the server you want to monitor is hidden behind a strict firewall only allowing access from a set of specific IP addresses? You can set up a server or process on one of those IP addresses to monitor and generate an XML file. Then there might not be a default check that is usable. The imagination is the limit. Let’s say you have a proprietary server that is using some binary protocol to communicate. Nothing stops you from performing more advanced tasks than the ones mentioned above. The number of active connections to your web serverĭid that vintage watch finally show up on Etsy? With Pingdom’s custom check, you’ll be the first to know.The amount of free RAM or HD space on your server.You can even monitor your broadband connection at home (so if you’re service provider claims you have 100% uptime, you can hold them to their word). And if you’re bidding on Ebay, you could use Pingdom’s custom check to alert you when a new bid comes in. If you’re looking to buy something that’s out of stock, you can search for a keyword (out of stock in this case) and see when that item becomes available. You can automatically detect content changes on the release page and immediately get alerted. Let’s say you’re interested in the latest release from Apple. ![]() This allows more comprehensive checks that go beyond a simple ping. Get the ability to call your own scripts on the server and set your own status report. It’s a kind of universal check type that you can customize as you wish on your end, a type of monitoring that store a value and a status of your choosing, based on a script on your servers. And using Pingdom’s custom checks, you can look for content changes on any website.Ī HTTP custom check hits a predefined endpoint that can execute scripts to determine the status of your site. With Pingdom, you can monitor your entire infrastructure – everything from your email server to your content delivery networks. Use the uptime command with -h command line option to display help.With a little piece of code, you can do big things Use the uptime command with -V command line option to display the version information. If you want to specifically display just the date and time since when the Linux system has been running, use the uptime command with -s command line option. If you want to display the uptime in pretty format, use the uptime command with -p command line option. Root privileges are not necessary to perform this check. To display uptime, just type uptime and press enter.
