Mail alerts conversations
I think it would greate if you add some headers to your mails.
This will helps to mail program to create conversation for every alert and clean message for it.
Now we have only separate messages:
LMD... critical - Host1 Ping PingLossPercent
LMD... critical - Host2 Ping PingLossPercent
LMD... ***CLEARED***critical - Host2 Ping PingLossPercent
LMD... ***CLEARED***critical - Host1 Ping PingLossPercent
In my opinion, it will better if this message will create conversation for every alert:
LMD... ***CLEARED***critical - Host1 Ping PingLossPercent
LMD... critical - Host1 Ping PingLossPercent
LMD... ***CLEARED***critical - Host2 Ping PingLossPercent
LMD... critical - Host2 Ping PingLossPercent
As I know, the header is Thread-Index
