In the Filter section, you can further refine your search using several different fields. These are Text, Severity, Facility, Devices, Virtual Server (VS) and Real Server (RS). You can search using just one filter or multiple. The relationship between the fields is an implicit AND. For example, if you specify a device IP and a Real Server IP, only entries that contain both are selected for display. In addition, when you select one of these filters, you are presented with a list of the devices, Real Servers and Virtual Servers that Kemp 360 Central knows about.

  • Text: Type a plain text string in the Text field to filter the results further. This is a simple text search. Typing any text string selects all log entries that contain that text string anywhere in the entry. For example, if you type an IP address, the log viewer displays all lines that contain that IP address, regardless of what kind of device is assigned that IP address (LoadMaster, Virtual Service, Real Server, and so on).
  • Severity: There are a number of levels of severity you can use in your search to filter the log search results. These are shown in the table below:

  • Facility: The Facility filter enables you to select the type of log issue you want to search for. For example, kernel messages, user-level messages, mail systems, system daemons, and so on. To select a facility, click the drop-down arrow.
  • Devices, VS, RS: You can also filter results on specific devices, Virtual Services and Real Servers. The list is arranged by device type, that is, all LoadMasters, all F5 devices, all NGINX devices, and so on, are listed as a group. If you select a device type for the search (for example, click LoadMaster), then all logs for all LoadMasters are searched. If you pick a specific device, then only logs for that device are searched.

Any field that you use in a search is highlighted. To exclude a filter in a search, click the X on the right of the field. In addition, logging is user-specific. If you log out and log back in again, any data that you used in your search will still be visible, however, it will not be visible to other users.

  1. Click Search to filter the results based on the specified criteria.

Note: To export all log data, select Everything from the Range, clear any filters that have been set by clicking the X next to them, click Search, and then click Export.
