Hello,
I would like to write a routine to monitor services running on a
remote box. My initial thought is to "ping" the remote box to monitor
latency and then execute a query on the remote machine to monitor the
database. What I would like is to gather data points and graph the
delay to see if there are any patterns;
A) Is this a sound strategy?
B) Are there libraries for the "ping"ing aspect? If not, I can
execute the ping using "command"...how can I capture the screen output
to get the times?
Pinging is actually a more complex beast than you might imagine.
If you know what ports the services are running on, or at least if
you know one service a box *should* be running, you could do
worse than to attempt a socket connection to that port number. For
example, seeing if a (not desperately secured) Windows box is
up is a question of attempting a connection on port 445. Likewise,
seeing if a web server (box) is running, you can try port 80. etc.
