Ping (ICMP)
Ping (ICMP) Ping is request message for protocol ICMP.

Ping is request message for ICMP (stands for Internet Control Message Protocol). This protocol is used by different network devices to check if a service or a device is available. Usually it is used for network diagnostics.

Ping monitoring allows you to keep an eye on your network infrastructure. Ping failure means broken connection to a network entity. It is handy to use Ping together with HTTP monitoring. In this case, you get additional information - for example, you know if the error is site-related, or the whole server has gone down. However, sometimes ICMP could be blocked for incoming requests, in order to prevent ddos attacks.

I like to know when my services are down, and how much time does it take to recover.

snapshot - instrument for site supervision

How does the site look like when I’m not looking at it? What if it looks bad or does not work at all? HostTracker offers an instrument for site supervision - snapshot feature. Let’s take a look at its practical application.

How does the site look like when I’m not looking at it? What if it looks bad or does not work at all? HostTracker offers an instrument for site supervision - snapshot feature. Let’s take a look at its practical application.

What’s going on with my site?

Now it’s usual to use different services and applications for site maintenance and support, and sometimes they do report some problems. Often we feel the lack of information - Google Analytics or a similar service reports the downtime and renewal, but likely we will never know what exactly has happened. To investigate the issue, it is necessary to review the logs, write to hosting support and perform many others exhausting actions, frequently - with no result. There are also more interesting cases - when a site is not available from a certain country or is not downloaded completely. Such problems could long for months, or even years, till they are accidentally detected. One more important issue - content check. It will automatically review the content of the site and informed the responsible staff in case it has disappeared - for example, something has not been able to be downloaded from the database. But it’s hard to find the cause if the issue is short-term, because people usually do not sit in front of a laptop refreshing the page every minute. To resolve the problem, HostTracker offers a new feature - snapshot. It is very simple in use and does not require any additional adjustments. The service simply makes a snapshot of the checked page every time and saves it for review in two ways: page source code and html-view. This let you easily see how the page looks at the moment of failure, understand what’s wrong and fix the problem quickly without spending time for diagnostics. It saves lots of time for server administrator, developers and other concerned people.

How does it work

Doing the regular checks, our servers with predefined interval try to download the checked page. Additional algorithms could be used at the moment - the page could be parsed for keywords to make sure that this is the one we are looking for (there are cases when an error page returns 200, Ok, http code, or when redirection is activated in case of error). If there is no error - fine. But if there is, it will be written down into the HostTracker log, which is easily available from the web. Then, notification are sent and a snapshot is made.

 

The snapshots could also be found in the log - if several errors were detected, a different snapshot will be available from each one.


Though there are some remarks. First, we do not run javascript while making snapshot - same thing for regular check. Second, the error must be detectable. I mean, the server must return something. In case of timeout or connection error - snapshot will not help, and only a corresponding record will remain in the log.

"Thank you so much for your service. We were suspecting problems with our hosting company but they denied any problems saying the issues must be at our end. We know we do have issues at our end but still suspected that wasn't the entire story. Your service was able to prove that they are indeed going down regularly - on average twice a week during the trial period. Thanks again for providing the information we needed to make a proper decision on this issue."
