How to find the number of hosts being polled in the NMS's polling log to decide the time interval of polling?
1. The NMS's polling log is stored in $n2000/server/log/ma5600v3_autopoll.log0. Take the MA5600 as an example. Other devices have corresponding log files. The value $n2000 stands for the n2000 installation directory.
Open polling log through UltraEdit, cut a day's log and count the number of Finish poll task fields. This number is the number of MA5600 devices polled in a day. In UltraEdit, search Finish poll task, and UltraEdit counts the total number of search results.
2. If the number of polling is fewer than the number of device types in the network, prolong the polling time. The polling time can be modified through the following steps:
Edit the POLL_TIME_START (start time to poll MA5600) and POLL_TIME_END (end time to poll MA5600) in the file $n2000/server/conf/ma5600v3/frame/bms_devpoll.cfg. Then restart the corresponding background process of MA5600 network elements to make the change take effect. Other parameters related to mid-night polling can also be modified in this file.
By default, the N2000V2 polls all devices across the network daily at 0:00 to synchronize device data. The number of devices being polled can be found in the polling log created after the polling. This number can be used to decide if it is necessary to prolong the polling interval to complete the polling of devices across the network.
It is recommended to change the time interval of polling according to the number of polled hosts in the log file to poll all devices across the network.
