Perform a PS

Performs a ps on the system.

Perform a Top

Performing a top command displays memory, CPU, and I/O usage for the LoadMaster. You can specify the number of samples and an interval between them (the default is 10 samples and a 1 second interval). You can also show threads and/or sort by memory usage by selecting the appropriate check boxes. By default the results are sorted by CPU usage.

Include Top in Backups

By default, the LoadMaster does not include a top output in backups. This can be enabled by selecting this check box. When included in backups, top is run using the default parameters (regardless of what is configured in the WUI) and is sorted by memory usage.

Display Meminfo

Displays raw memory statistics.

Display Slabinfo

Displays raw slab statistics.

Perform an Ifconfig

Displays raw Ifconfig output.

Perform a Netstat

Displays Netstat output.

Include Netstat in Backups

By default, the LoadMaster includes a Netstat output in backups taken. When this is included, backups take longer to complete. You can stop the Netstat output from being included by disabling this option.

Netconsole Host

If directed by a Progress Kemp support engineer, you can use this feature to send critical kernel logs to a syslog server in the event of the LoadMaster failing or crashing. A syslog server configured as the Netconsole Host receives all critical kernel messages.

You can select which interface the Netconsole Host is set to using the Interface dropdown.

Note: Please ensure that the Netconsole Host IP specified is on the selected interface as errors may occur if it is not.
Note: The Netconsole Host parameter can be set to either an IPv4 or IPv6 address, the only restriction being that the Netconsole IP address must be in the same address family as the LoadMaster’s IP address on the selected Interface. In other words, if the LoadMaster’s IP address on the selected Interface is an IPv4 address, then the Netconsole Host IP address must be an IPv4 address as well. If you want to use an IPv6 address for Netconsole Host, then you must select an Interface on which the LoadMaster has an IPv6 address.
Note: Netconsole is not configurable on a bonded interface.

Ping Host

Performs a ping on the specified host. The interface which the ping should be sent from can be specified in the Interface drop-down list. The Automatic option selects the correct interface to ping an address on a particular network.

The interface tries to determine if the address to ping is an IPv4 or IPv6 address and selects the correct command to perform the ping. For an address in numeric form this is simple, however this is not possible for non-numeric addresses so they will always be treated as an IPv4 address.

Ping6 Host

Perform a ping6 of a specific IPv6 host.

Traceroute Host

Perform a traceroute of a specific host.

TCP dump

A TCP dump can be captured either by one or all Ethernet ports. You can specify the address and port parameters in the WUI. To specify additional, optional parameters - use the Application Programming Interface (API) to perform a TCP dump.

You can stop and start the dump. You can also download it to a particular location. The results of the TCP dump can then be analysed in a packet trace analyser tool such as Wireshark.
