This document describes how to uninstall, restart, and stop CVM Agents.
CVM Agents include Sgagent and BaradAgent. Sgagent reports component information update and triggers BaradAgent, and BaradAgent reports CVM metric data.
The procedures for Linux and Windows are different. You can refer to the following directions as needed.
Log in to the CVM instance and run the following command to go to the installation directory of BaradAgent:
cd /usr/local/qcloud/monitor/barad/admin
Run the following command to uninstall BaradAgent. Note that this command does not output the result. If the /usr/local/qcloud/monitor/barad
folder does not exist, BaradAgent has been uninstalled successfully.
./uninstall.sh
Note:BaradAgent reports some of the CVM metric data. Once uninstalled, BaradAgent stops reporting data. Sgagent consumes just a little memory. If you need to uninstall Sgagent, please refer to the following directions.
Run the following command to go to the installation directory of Sgagent:
cd /usr/local/qcloud/stargate/admin
Run the following command to uninstall Sgagent. This command does not output the result. You can run the crontab -l |grep stargate
command to check whether there is any scheduled task. If not, Sgagent has been uninstalled successfully.
./uninstall.sh
Run the following command to go to the installation directory of BaradAgent:
cd /usr/local/qcloud/monitor/barad/admin
Run the following command to restart BaradAgent. If barad_agent run succ
is displayed, BaradAgent has been restarted successfully.
./stop.sh
./trystart.sh
Run the following command to go to the installation directory of Sgagent:
cd /usr/local/qcloud/stargate/admin
Run the following command to restart Sgagent. If stargate agent run succ
is displayed, Sgagent has been restarted successfully.
./restart.sh
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, please stop both Sgagent and BaradAgent in sequence by referring to the following directions:
Run the following command to delete the scheduling Sgagent files:
rm -f /etc/cron.d/sgagenttask
Run the following command to enter the crontab file:
crontab -e
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.
Stop Sgagent.
Run the following command to go to the installation directory of Sgagent:
cd /usr/local/qcloud/stargate/admin
Run the following command to stop Sgagent:
./stop.sh
Stop BaradAgent.
Run the following command to go to the installation directory of BaradAgent:
cd /usr/local/qcloud/monitor/barad/admin
Run the following command to stop BaradAgent:
./stop.sh
Note:After the command is successfully executed, the service will not be started automatically, and the monitoring data will be lost. To restart the service, both these two Agent services need to be restarted.
Run services.msc
to open the Services Manager to find BaradAgent and Sgagent, as shown in the following figure. Then, right-click a service to start, restart, or stop it.
Open cmd and run the following commands. After "[SC] DeleteService succeeds" is displayed, restart the CVM instance.
sc.exe delete "BaradAgentSvc"
sc.exe delete "StargateSvc"
