Network Services and Ping Monitoring

    I'll start with the story. When Ping-Admin.Ru was just being developed , we decided right away that we would not do ping testing. Yes, most monitoring services have such a check, but we refused it and here's why:
    1. Most users will choose ping for verification without thinking about what ping actually does.
    2. If the address is pinged, it only means that the server itself is turned on and the OS is running on it. And the fact that Apache, DB, mail works there does not mean at all. And therefore, there are often situations when the address responds, and the site at this address does not open or opens with an error. Those. You always need to monitor the necessary service on the server, and not just ping the address.
    3. If the address does not respond, then this does not mean anything, because quite often there are blocking ICMP packets, because of which ping does not pass, but at the same time, everything else works fine.

    But just a few days ago, such a letter came:
    I serve a number of offices that have servers on FreeBSD and that act as a router.
    Of course, they will call me if some server stops working, but I would like to know about it more quickly.
    And I don’t really want to specifically raise Apache servers or something else just to check if the server is working or not.

    There really is nothing but ping (if you do not take any complete perversions), it will not work to check the operation of the servers.

    So, in a hurry to share the good news, we have ping. Now the site address: Ping-Admin.Ru began to justify its name even more :-)
