From the Activity dashboard, you can monitor general information about application activity and performance from the transport through the application layers (L4 - L7) on your network.
Each chart in the Activity dashboard contains visualizations of protocol metric data, organized by region. You cannot edit or delete the Activity dashboard. However, you can create your own custom dashboard to monitor specific metrics that are relevant to you.
The following information summarizes each region and its charts.
- Traffic Overview
- Determine whether traffic bottlenecks are related to a specific application protocol or
network latency. The Traffic Overview region contains the following charts:
Network Packets by L7 Protocol Avg Rate chart: Find the protocol that has the highest volume of packet transmissions over the application layer (L7) during the selected time interval.
All Activity Network Round Trip Time: The 95th percentile line shows you the upper range of the time that it took for packets to traverse the network. If this value is over 250ms, then network issues could be slowing down application performance. Round trip time is a measurement of the time between when a client or server sent a packet and received an acknowledgment.
Alert History: View up to 40 of the latest alerts that were generated, and their severity levels. Alerts are user-configured conditions that establish baseline values for specific protocol metrics.
- Active Protocols
Determine how application performance is affected by the protocols that are actively communicating over the wire. For example, you can quickly glance at charts that display server processing times and the ratio of errors to responses per protocol.
There is a chart for each active protocol. If you do not see a protocol you were expecting, applications might be not communicating over that protocol for the selected time interval.
