The data storage in the environmental monitoring database is generally defaulted as 500 thousand records. If the data is exceeded, the earliest data will be deleted. However, when managed network elements are rather many, 500 thousand records are only equivalent to the data in one to two days. When more data is needed to be saved, how to modify?
1.Open the file \n2000\server\conf\main\enpowerdm\enpowerdm.cfg;
Find # to save the maximal historical data
SaveHisDataMax = 500000
Change 500000 to the data required, such as 2000000, and save the file.
What needs to be noted is that it is not recommended to use large data, which may take enormous data space.
If the saved data exceeds 10 million strips, it may result in the abnormity of environmental database.
2.Open the NM sysmonitor, find the background of environmental monitoring, and close the background of environmental monitoring.
3.Restart the background of environmental monitoring.
The environmental monitoring database mainly saves some changing data of environment parameters. Generally, the data is not required to be saved in large quantity. The environment alarm can be queried by querying the alarm database for failure history
