- If you upgrade the Node.js agent from Cloud APM V8.1.3.2 to V8.1.4, complete the following procedure:
  - If you enabled resource data collection, remove the following line from the beginning of the Node.js application file:
```
require('KNJ_NPM_LIB_LOCATION/node_modules/ibm-apm/knj_index.js');
```
    where KNJ_NPM_LIB_LOCATION is the directory to the lib folder of your npm package global installation directory. The default directory is /usr/local/lib.
  - If you enabled resource data collection and deep-dive diagnostics data collection, remove the following line from the beginning of the Node.js application file:
```
require('KNJ_NPM_LIB_LOCATION/node_modules/ibm-apm/knj_deepdive.js');
```
  - If you enabled resource data collection, deep-dive diagnostics data collection, and method traces collection, remove the following line from the beginning of the Node.js application file:
```
require('KNJ_NPM_LIB_LOCATION/node_modules/ibm-apm/knj_methodtrace.js');
```
- If you upgrade the Node.js agent from Cloud APM V8.1.3 to V8.1.4, complete the following procedure:
  - If you enabled resource data collection, remove the following line from the beginning of the Node.js application file.
```
require('install_dir/lx8266/nj/bin/plugin/knj_index.js');
```
    , where install_dir is the installation directory of Node.js agent.
  - If you enabled resource data collection and deep-dive diagnostics data collection, remove the following line from the beginning of the Node.js application file.
```
require('install_dir/lx8266/nj/bin/plugin/knj_deepdive.js');
```
  - If you enabled resource data collection, deep-dive diagnostics data collection, and method traces collection, remove the following line from the beginning of the Node.js application file.
```
require('install_dir/lx8266/nj/bin/plugin/knj_methodtrace.js');
```
Restart your Node.js application to disable the data collector plug-ins.
- If the version of your current Node.js agent is Cloud APM V8.1.3, till now the data collector plug-ins are successfully removed.
- If the version of your current Node.js agent is Cloud APM V8.1.3.2, continue to the following step.
Run the ./uninstall.sh command from the install_dir/lx8266/nj/bin directory to remove your previous agent settings.
