Error types
You can enable/disable receiving alerts for the different error types and also configure different alert messages for every error type. Currently there are 3 error classes:
Connection errors - these errors indicate different problems with the network connection to the monitored target which include DNS lookup problems and TCP/UDP connection issues (Connection Refused, Network/Host Unreachable, Connection timed out, No route to host, etc.). When monitoring PING only devices you can also receive a "100% packet loss" error which is also related to the network connection to the monitored target.
Content errors - this class includes all errors detected after our monitoring agent has successfully connected to your server. The most common "Content errors" are "Internal server error", "File not found", "Keywords found/not found", "File size check failed", "MD5 hash check failed", SSL handshake errors, etc.
Timeout warnings - this error type includes all timeout warnings which occur when the monitored target is responding properly but the response time is higher than the specified timeout limit.
