Service (port) Monitoring

apeterson · Post by **apeterson** » Fri Sep 09, 2005 2:34 pm

Rather than only checking for up/down status using either snmp, ping or both, how about also checking specific tcp/udp ports either instead or in addition? Maybe even send a string and expect a response?

not quite the same.. but might be of use to you. I just use it with thold

adaptation of the ping-tcp.pl script to check if a connection can actually be established to a port.

perl <path_cacti>/scripts/tcp.pl <count> <ip> <port>

Karpet,

Please see the 0.8.6g addon call ss_fping.php. It supports the following format through the Script Server:

php ss_fping.php <hostname> <count> <type> <port>

<hostname> - Host DNS or IP
<count> - Number of connection attempts
<type> - ICMP, TCP, UDP
<port> - TCP/UDP Port to SYN

You may find that it's faster.

I implemented ss_fping from the 1.2 version posted. I remember now why I stopped using it. It polls correctly (even with the new version and parameters) but something about the graphs doesn't work because cacti will not display them. Instead I get those awesome red X's as if it can't find the image/file. I don't believe the graph ID is getting recorded properly wherever that info gets recorded.

Can you offer any assistance?

Goto "Graph Management", edit one of the graphs in question. Once it's edited, there will be a Graph Debug link in the upper right corner. Please post the result of that DEBUG as well as the graph syntax.

To get the graph syntax, you must run in DEBUG mode and view the graph again. You can then goto the log and you will find a "CACTI2RRD" statement followed by the graph syntax.

The debug output is non-existant other than a red X so I've attached it instead.

The graph syntax is:

Also, this is on Win2k. Is it possible this is the 2048 character limitation I read about? It certainly won't run that command from a command prompt window because it's way too long.

What is your Operating System?

Win2k (Server).

Yes, that appears to be the problem. I want to rewrite the template, it will take a while. If you recreate the graph with a very short name, let the RRD be created and then rename the graph, you will have a workaround though.

You're right. I did what you said and it works now. I look forward to your update and thanks so much for the help!

No errors in the log in debug and the graphs are now accessible BUT empty. More fun with this on Monday...
