Logging Settings

The Logging Settings section is used to configure how and where the device stores system log data. The system log is a file that contains information on various system related events and is useful to engineers for troubleshooting the device.

Field Value Description
System log buffer size integer; default: 128 System log buffer size in kibibytes (KiB).
External system log server Hostname host:port; default: none IP address/host and port of an external server that will be used to store device logs.
External system log server Protocol UDP | TCP; default: UDP Communication protocol used by the external log server.
Save log in RAM memory | Flash memory; default: RAM memory Specifies which type of memory to use for storing system logs.
System log file size integer [10..500]; default: 200 Maximum size (in kilobytes) of a log file. When threshold is reached, log rotation is performed. Can be set to value from 10kB to 500kB. Smaller the file, larger amount of old logs is saved.
Compress off | on; default: off Compress old rotated logs using GZ format.
Delete - (interactive button) Deletes log file from router.
Show hostname off | on; default: off Show hostname instead of IP address in syslog.

Troubleshoot

The Troubleshoot section is used to download various files that contain information used for troubleshooting the device. Refer to the figure and table below for information on the Troubleshoot page.

Field Value Description
System log - (interactive button) Displays the contents of the device system log file. The system log contains records of various system related events, such as starts/stops of various services, errors, reboots, etc.
Kernel log - (interactive button) Displays the contents of the device kernel log file. The kernel log contains records of various events related to the processes of the operating system (OS).
Encrypt off | on; default: off Turn on AES 256 encryption and archive Troubleshoot file using zip format.
Password string; default: none Password that will be used to encrypt Troubleshoot file. It will have to be provided when extracting formatted zip archive to gain access to a tar file.
Troubleshoot file - (interactive button) Downloads the device Troubleshoot file. It contains the device configuration information, logs and some other files. When requesting support, it is recommended to always provide the device Troubleshoot file to Teltonika engineers for analysis.
TCP dump file* - (interactive button) Downloads the device TCP dump file. TCP dump is a program used to capture packets moving through network interfaces. By default, the device does not store TCP dump information. You must enable TCP dump and save the changes before you can download the file.
Enable TCP dump* off | on; default: off Turns TCP dump packets capture on or off.
Select interface Any | LAN | WAN | WLAN; default: Any Only captures packets that move through the specified network interface.
Select protocol filter All | ICMP | TCP | UDP | ARP; default: All Only captures packets that match the specified protocol.
Select packets direction Incoming/Outgoing | Incoming | Outgoing; default: Incoming/Outgoing Only captures packets coming from the specified direction.
Host Domain names or IP; default: none Only captures packets related to the specified host.
Port integer [1..65535]; default: none Only captures packets related to the specified port.
Select storage RAM memory | ; default: RAM memory Specifies where the TCP dump file will be stored.

* As of {{{series}}}_R_00.07.00, TCPdump is not part of core functionality anymore. To see these options, the TCPdump package must be downloaded from [[{{{name}}}_Package_Manager|Package Manager]].

Diagnostics

The Diagnostics section is used to execute simple network diagnostic tests, including ping, traceroute and nslookup.

Field Value Description
Method Ping | Traceroute | Nslookup; default: Ping Selects diagnostic method.
  • Ping - sends ICMP requests to the specified address.
  • Traceroute - displays the path that packets have to take in order to reach the specified address.
  • Nslookup - obtains domain name address and IP address mapping information.
Protocol IPv4 | IPv6; default: IPv4 Selects IP address family for diagnostic test.
Address ip | host; default: none IP address or hostname on which the diagnostic test will be performed.
