Go to Network Analysis > Performance > History to begin viewing aspects of the historical behavior of all network devices on the managed network.

To work effectively with the charts on this page, choose any menu option on the left (History > Routes, for example), and then choose a device group from the menu on the right. The data set that is shown in any Performance, History, or Environment page will change to show the data specific to the chosen device group.

  • Devices: This page summarizes the total number of devices found on the network for the reporting period, and those found for each of the last 30 days. Data sets can be shown for individual device groups. The summaries come in the form of bar charts and in data tables listing the basic data sets comprising the device types and the states the devices were in when discovered. For more information, see Device History Summaries.

  • HSRPs/VRRPs: Shows the number of distinct HSRP and VRRP groups found on the network during the 30 days before the selected date.
    For more information, see HSRP/VRRP Summaries.

  • Issues: Summarizes the number of issues by severity and difference type. For more information, see Viewing Issue Summaries.
    Most networks have at least a couple of issues generated each day. If the trend stays relatively constant or decreases over time, things are normal.

  • Reboots: Shows the number of reboots detected for router and switch devices for 30 days before the selected date. Frequent reboots, or large numbers of reboots, could indicate a problem.
    See the Troubleshooting Device Reboots topic for more information on this feature.

  • Routes: Shows the number of routes discovered on the network during the 30 days before the selected date. For more information, see Summarizing Routes.

  • Subnets: Shows the number of subnets found on the network during the 30 days before the selected date. For more information, see Summarizing Subnetworks.

  • VLANs: Shows the number of distinct VLANs found on the network during the 30 days before the selected date. Investigate changes in the number of VLANs. For more information, see Summarizing VLANs.
