Maintenance mode

Sometimes you want to do some work on a server without stopping the actual checkin of this server. Also you don't want to get allerts from Servers Alive saying that this server is down. Therefore the concept of MAINTENANCE was introduced.
Once a server/host entry is put into MAINTENANCE mode, it will be flagged as being in MAINTENANCE and Servers Alive will no longer try to test it.
There are several ways to put a host into maintenance mode.

  • On the ADD/EDIT host screen you can EXCLUDE the server from the check cycles.
  • You can right click on the server name and select to put it into maintenance mode.
  • You can set it into maintenance mode via the telnet interface
  • You can use the MAINTENANCE utility to do this remotly. (To make this utility work, the build-in telnet server of Servers Alive must be running)
  • Note :
  • The hostname is the name (or ip address) of the machine running Servers Alive !
  • But you can also run this utility with commandline (this can be very handy if you want to schedule this via AT (on NT))

    What Host number to use?

    This is a sample TelNet session to Servers Alive :

    So if you want to put products (port 53) into maintenance mode, you must use 7 as host number.
