To experience better CLS log collection service, you can upgrade the LogListener automatically or manually via the console or semi-automatically via scripts. After the LogListener version is upgraded, you don't need to download the latest-version installer. You can set a time period for auto upgrade or select specific machines to upgrade manually by one click.
The auto upgrade feature requires Python 2. If Python 3 is installed on the collection machine, the upgrade process will not be fully executed.
The script-based semi-auto upgrade feature requires Python 2.7. If this version is not installed on the collection machine, this upgrade mode cannot be used.
You can choose auto upgrade or manual upgrade for LogListener in the console.
If Agent upgrade fails or auto upgrade cannot be used due to version restrictions, you can use the semi-auto upgrade mode.
2. On the left sidebar, click Machine Group to enter the management page.
3. Find the target machine group, move the cursor under
in the Auto Upgrade column, and click Enable Now.
4. In the pop-up, toggle the button on and specify the upgrade time period (the default period is from the current time to two hours later, such as 08:39-10:39).
5. Click OK. When the status of the target machine group changes to Enabled as displayed in the Auto Upgrade column, auto upgrade has been enabled successfully.
Note:
You can set any time period for the auto upgrade, and the system will check if upgrade is needed every day in the specified time period. If the upgrade conditions are met, the auto-upgrade will be performed; otherwise, the operation will be performed.
You can select multiple target machine groups and click Auto Upgrade to upgrade them in batches.
2. On the left sidebar, click Machine Group to enter the management page.
3. Find the target machine group and click Upgrade Now in the Operation column.
4. In the pop-up window, select the target machine with status as To be upgraded and click Manual Upgrade.
The system will upgrade LogListener to the latest version by default. When you see This is the latest version, the manual upgrade is successful.
Note:
When the status is Unable to upgrade, you cannot upgrade the LogListener in the console, and you need to download the latest-version installer to upgrade. For details, see LogListener Installation Guide.
Here, x in loglistener-linux-x64-x.tar.gz represents the version number of LogListener to upgrade to (such as 2.7.2). The latest version of LogListener is as displayed in LogListener Installation Guide. If the entered version does not exist, the download will fail. If the version entered is earlier than the current version installed on the machine, the upgrade will not take effect.
