CACTI monitors the added host state through the SNMP protocol every interval , and in the Cacti database, Host The table records information about the switch, such as status, the most recent downtime (status_fail_date), and the most recent return to normal time ( status_rec_date). To implement fetion monitoring switch status, the switch sends text messages to the specified phone number, and the switch information for the outage cannot be repeated. Idea: Determine the status of the switch (the outage only sends a message once), whether to send text messages. Add the current state of the switch (status_now) and the default switch state (Status_default) in the host table two columns, with a default value of 1 for Normal, are used to compare with the last switch state so that no recurring messages are repeated. The code is as follows: ALTER TABLE ' Host ' ADD COLUMN ' Status_now ' char (2) Not NULL DEFAULT ' 1 ' after ' availability '; ALTER TABLE ' Host ' ADD COLUMN ' Status_default ' char (2) Not NULL default ' 1 ' after ' Status_now '; 1. Recent outage time ; Last recovery time- ; switch down- ; Change record status=0; at this time status columns and Status_default The column values are 0 , 1 - ; Send SMS- ; Change Record status_default=0; at this time status columns and Status_default The column values are 0 , 0 - ; detect switch downtime again, do not relapse SMS ; 2. Recent outage time <= Last recovery time-> Switch back to normal-> change record Status=1; at this Status columns, and Status_default the values for the columns are 1 , 0 - > Send SMS- > Change Record status_default=1; at this Status columns, and Status_default the values for the columns are 1 , 1 - > The switch has not sent a text message. From the above you can see that the switch has undergone four state changes :
| status_now status_default |
|
1 |
1 |
Normal, no SMS notification |
0 |
1 |
downtime, SMS notifications |
0 |
0 |
detect downtime again, no SMS notifications |
1 |
0 |
return to normal, SMS notification |
We just need to determine four states and then remove the switch description from the host table ( description ) to a string to submit to Fetion API can.
