Webpage Analyzer - Troubleshooting
Prerequisites:
- Web Page Accessibility: Ensure the web page monitored is accessible from the machine where the Applications Manager is installed.
- Proxy Configuration: If a proxy is required to access the URL, ensure that the same proxy settings are configured within the Applications Manager. Click here to learn how to configure the proxy.
- Bypass Proxy: If you have configured a proxy in Applications Manager, but want to bypass it for the URL, add the corresponding host/IP under the "Do not use proxy for addresses beginning with" section in the "Configure Proxy" page: Navigate to Settings > Product Settings > Proxy Server Settings.
- Headers & Request Parameters: If specific headers or request parameters are needed, configure them accordingly in the Applications Manager.
Troubleshooting
1.Not able to add monitor
- Check if the web page is accessible from the machine where the AppManager is installed.
- Refer here to know more about the URL related errors.
2.Getting "Kindly install all addons to get data in Network Log,Resource Details and PageSpeed Insights tab"
- Ensure that the required add-ons for data collection are downloaded from the provided link and placed under the
<APM home>/workingfolder. - If the error persists, verify whether the user has downloaded the correct add-on based on their operating system. Additionally, confirm that the add-ons are correctly placed as per the prerequisites mentioned on the help page.
- Wait for 2-3 polls to see if the error message continues to appear.
3.Getting "Data collection failed : Unable to setup browser for data collection"
- Go to <APM home>/working/wpaAddons/Browser/Mozilla Firefox and launch firefox.
- If you get an error like library not found, install the required library.
- If you see "Permission denied", grant execute permission to all users.
- Go to <APM home>/working/wpaAddons/GeckoDriver and grant executable permission to the geckodriver for all users.
- Wait for 2-3 polls and check if the issue persists.
4.Getting "Data Collection Interrupted"
- This issue typically arises when data collection for all WPA monitors occurs simultaneously. Since Firefox launches in headless mode during each poll to collect data, it’s important to maintain a minimum poll interval between all WPA monitors to avoid conflicts.
- Wait for 2-3 polls to see if the issue persists.
5.Getting "No data available" error message in Pagespeed Insights tab. Refer here
