Do this already, in the same and different ways. It all depends on what's available for network failure detection on the site. I always prefer snmp for this. But there are sites where it's not possible to do so. > For the counter, you could use a file and modified it from ifstated, > and do a if grep 10 /my/file > echo "my file reach 10"| mail -s alert root; call real action; erase file, I use a database for this. Used files in the beginning but improved to a database. But I need to wait a state change and/or I need to have a <run every> statement that will make the decision. But, since It's only a boolean, I need to have several <run every> statements to be able to cover all cases. This makes the ifstated daemon a little slower, so the overall link failure detection takes more time. > > but lets wait for people with more insight :-) Yes. I'll probably hack it anyway. But if more people here on tech@ helps with suggestions/directions, I'll probably do a better job. Thanks in advance for your time.
