Hi Dave,
Thanks a lot for your fast reply! :-)
Sorry, but I still don't see the solution.
So, I have my Cricket instance configured for monitoring one parameter in 2
hosts (maybe I should post that in the Cricket's mailing list too). That means
I have something like:
[Cricket config]
datasource param1-host1
ds-source = snmp://[EMAIL PROTECTED]:161/<oid for param1>
datasource param1-host2
ds-source = snmp://[EMAIL PROTECTED]:161/<oid for param1>
So, I send the same OID to the same SNMP instance! That means it has no way to
know that the first goes to host1 and the second to host2.
Let's suppose I have configured /etc/hosts
127.0.0.1 localhost host1 host2
and Cricket like:
[Cricket config]
datasource param-host1
ds-source = snmp://[EMAIL PROTECTED]:161/<oid for param1>
datasource param-host2
ds-source = snmp://[EMAIL PROTECTED]:161/<oid for param1>
Does that help?
Thanks again,
Isi,

+ Several scripts (or several links to the same script), and use
the name of the invoked script to determine which host to query
For example
$ ls -l /usr/local/snmp2http/hosts
lrwxrwxrwx ..... host1 -> ../script
lrwxrwxrwx ..... host2 -> ../script
lrwxrwxrwx ..... host2 -> ../script
$ head /usr/local/snmp2http/script
#!/usr/bin/perl
$remote_host = $0;
<etc, etc>
