Hi Santosh,
I don't think you would be able to get a list of Chassis Down Alarms for the last 45 days (including the cleared alarms).
Perhaps, you could try to search for the event 0x10f69 which generates Critical Alarm for Chassis Down for the last 45 days to know the count of Chassis Down Alarm following the below procedure:
On your SpectroSERVER, navigate to $SPECROOT/mysql/bin directory from command prompt
Logon to mysql by typing the following:
mysql.exe --defaults-file=../my-spectrum.cnf -uroot -proot ddmdb -A (For Windows)
./mysql --defaults-file=../my-spectrum.cnf -uroot -proot ddmdb -A (For Non Windows)
Now, to find the occurrences for the event 0x10f69 for the last 45 days, i.e. from midnight of 1st Oct 2017 till 5PM, 14th Nov 2017, in our case, type:
SELECT hex(model_h), count(*) as c from ddmdb.event where utime > UNIX_TIMESTAMP('2017-10-01 00:00:00') and utime < UNIX_TIMESTAMP('2017-11-14 17:00:00') and type=0x10f69 group by hex(model_h) order by c desc;
You would now see the number of occurrences for the event 0x10f69 with its model handle. Example from my in-house box:
+--------------+----+
| hex(model_h) | c |
+--------------+----+
| 1000CD | 24 |
| 10006E | 5 |
+--------------+----+
2 rows in set (0.00 sec)
Best Regards,
