./uninstall.sh
Restarting Agents

Stopping Agents
Note:
The report of CVM metric data will only be stopped unless both Sgagent and BaradAgent are stopped. You can Stop BaradAgent to suspend data report for a while. However, BaradAgent will resume data report in one minute as it will be triggered by Sgagent. Therefore, to stop data report, stop both Sgagent and BaradAgent in sequence by referring to the following directions:
1. Run the following command to delete the scheduling Sgagent files:
rm -f /etc/cron.d/sgagenttask
2. Run the following command to enter the crontab file:
crontab -e
3. Press i to switch to the editing mode to delete the file information. After it is deleted, press Esc and enter :wq to save the file and exit.
4. Stop Sgagent.
