    A HAR archive of the network timings from a compatible browser is extremely useful in pinpointing which issues with Kibana talking to Elasticsearch.

    ## Note on information gathered in a HAR archive

    Please note that HAR archives contain sensitive information:

    - content of the pages you downloaded while recording
    - your cookies, which will allow anyone with the HAR file to impersonate your account
    - all the information that you submitted to your browser while recording (i.e., search values, authentication details).


    ## Browser Instructions
    **Chrome**
    You can record your HTTP session using the Network tab in the Developer Tools in Chrome.
    - Open the Developer Tools from the menu (Menu > Tools > developer tools), or by pressing Ctrl+Shift+C on your keyboard
    - Click on the Network tab
    - Look for a round button at the top left of the Network tab. Make sure it is red. If it is grey, click it once to start recording.
    - Check the box next to Preserve log.
    - You can use the clear button (a circle with a diagonal line through it) right before trying to reproduce the issue to remove unnecessary header information
    - Save the capture by right-clicking on the grid and choosing "Save as HAR with Content"

    **Firefox**
    - Starting with Firefox 41, HAR files can be created without any additional extension.
    - Start Firefox Developer Tools in Network mode (Top right menu > Developer > Network, or ctrl-shift-Q)
    - Reproduce the issue
    - Save the capture by right-clicking on the grid and choosing "Save all as HAR"
    - Export the capture to a HAR file

    **Internet Explorer/Edge**
    Edge natively produces HAR files. See detailed instructions in the [Microsoft site](https://www.google.com/url?q=https://docs.microsoft.com/microsoft-edge/f12-devtools-guide/network)
    - Open the Network tool in F12 developer tools
    - Reproduce the issue
    - Export captured traffic as a HAR (CTRL + S)
    For Internet Explorer, you will need to use: [HttpWatch](https://www.google.com/url?q=http://www.httpwatch.com) .
    - Download and Install HttpWatch
    - Start the HttpWatch capture right before reproducing the behavior you want to study
    - Stop the HttpWatch capture right after reproducing the behavior to study
    - Export the capture to HAR format
