Identify Network Problems for a Device

Use the Network view to view network performance for the main device being examined, as well as for other related devices. A common network performance problem is when devices or hardware are not functioning properly.

On the Other Devices cards, you can optionally filter by attributes, such as Business Location. For example, set the Business Location filters to match the Business Location of the main device you are examining in order to see if that location is experiencing spikes or other network problems. If there was a big spike in network time for that office, then the network problem is not specific to this device, but it is specific to this location; however, if the spike is quite high for this device and quite low for the location, then it might lead you to a different conclusion.

Procedure

  1. Step 1 Open a browser and sign in to Aternity.
  2. Step 2 Use the search box in the top bar to quickly find a particular device.
    Finding a user, hostname, device, or application in Aternity

    You can enter a device hostname or IP address or enter the name of a dashboard.

    Note

    You can use spaces and other alphanumeric characters. This search is not case sensitive, so it will search for the text in any combination of upper and lower case characters. The search supports email addresses and @. The search does not support other wild cards (like *) or other forms of logic (and/or).

  3. Step 3 Select the Build Your Own tab.
    Select Build Your Own
  4. Step 4 Select the Network tab.
  5. Step 5 Adjust the time range within which you want to troubleshoot the device.
    To do so, drag the time blue gauge or only its right or left border. Alternatively, open the time picker and manually set the timeframe.
    Select the exact time period for your analysis

    You can also use the predefined buttons: Recent Week , Recent Day , Recent Hour , or Recent 15 min . To change the timeframe of the dashboard, use the timeline gauge on the top of the screen. The arrows on the time bar shift the time and blue gauge in a week or day or else, depending on the selected preset.

    Field Description
    Activity Network Time

    Network time is the total time (union) taken for all messages to cross the network in either direction, between the client and the target server, while performing an activity. This does NOT include the time used for processing the request on the server (backend time).

    The network time is calculated as the infra time minus the backend time.

    Network Web Delays
    The web page load time is the time required for a web page to load and finish rendering in a browser, from sending a URL request to when the page's events finish loading and it has a status of Completed. This measurement does NOT include the time to load additional page elements which occur after the main page has loaded, such as iframes that are embedded separate web pages, AJAX calls after the page is complete, or bookmarks with # in the URL). It does include AJAX calls that the page makes before it is complete.
    Field Description
    Page Load Response Time Avg

    Displays the average time between the first response from the server to the last response from the cache or the server, as part of the total load time of a web page.

    Page Load TCP Connect Time Avg

    Displays the average time required to establish the regular or secured TCP connection, as part of the total load time of a web page.

    Page Load Request Time Avg

    Displays the average time between the first request to the server, and the first response from the server, as part of the total load time of a web page.

    Page Load DNS Time Avg

    Displays the average time required to perform domain lookups with DNS, as part of the total load time of a web page.

    Agent Network Latency

    Displays a measure of network latency from the device to the Aternity server (reported by the Agent every 5 minutes for the main device you are examining). In other words, it is the time it takes the Agent to connect to Aternity.

    This metric is only supported on Agent 12.1.1 or greater, and will otherwise report No data in this card.

    WiFi Signal Strength Displays the percent strength of the WiFi signal which the device receives, which can impact communication speed. For more details, hover your mouse over the graph in the dashboard to see the name of the WiFi network connection (SSID), the wireless network card MAC address (BSSID), and the WiFi channel.
    CPU & Memory

    View CPU & Memory consumption for the selected device.

    Field Description
    CPU Util Avg

    Displays the average percent CPU usage for the device over the aggregation period, calculated from data that Aternity aggregates every two minutes.

    Physical Memory Util Avg

    Displays the percentage usage of the device's physical RAM memory at a given time, calculated from data that Aternity aggregates every two minutes.

    Health Events

    View Health Events that occurred on the selected device.

    A health event indicates a device or application encountered a significant error which affects the overall health of the user experience, like a corrupted disk or a system crash. There are three types of health events: application health events, hardware health events, and system health events.

  7. Step 7 To see which spike is which, hover over the legend to see the colored trend line.
    View the trend of the certain metric
  8. Step 8 Analyze the spikes by correlating data in different widgets. If there is no data available for a widget, change the timeframe. Probably, there are no records for the selected time. To see the data, select a wider time period.
  9. Step 9 Select a specific area on the chart and drag a mouse over it to zoom in on a certain time period. All widgets will change accordingly.

    Select Back to return to the previous time range. If you have zoomed in multiple times, select Back as many times as necessary to return to the initial view.
