Just now when i reach sg custom, receive per minute alert. As my personal linux server monitoring apps down.
I quickly open my iphone monitoring apps to check, really cannot connect the server.
I open SSH apps to check it. Found there is code problem i changed afternoon.
I open FTP Client Pro to edit the code.
Use SSH apps to restart the apps.
Then i received the good alert message.
Actually, I had a server monitoring apps to monitor some other apps. And had another apps to hourly monitor the server monitoring apps which hosts own other server. So as long as alert server is not down, the other servers down i still can get alert, and start it, they just works as expected.
