For example, we want to log NTP debug info without too much details:. Note: default actions can not be deleted or renamed. Each log entry have topic which describes the origin of log message.
There can be more than one topic assigned to log message. For example, OSPF debug logs have four different topics: route, ospf, debug and raw. You can specify maximum size of file in lines by specifying disk-lines-per-file. Note: Logging entries from files will be stored back in the memory after reboot.
These two screenshots will show you how to configure the RouterOS logging facility to send Webrpoxy logs to a remote syslog server, in this example, located at The syslog server can be any software that supports receiving syslogs, for example Kiwi syslog.
Add a new logging action, with "remote" and the IP of the remote server. Call it whatever you like. Then add a new logging rule with the topic "webproxy" and then newly created action.
Note that you must have webproxy running on this router already, for this to work. To test, you can temporary change the action to "memory" and see the "log" window if the webproxy visited websites are logged. If it works, change it back to your new remote action. Note: it's a good idea to add another topic in the same rule:! The first defines some system variables which are used in other scripts and the second does the grunt work:.
In v4. This integration allows users to create their own functions and bypass several command line scripting limitations. All examples below require at least basic knowledge of Lua scripting language.
Good tutorials can be found here as a starting point. As stated in Lua documentation, 'print' command is not available in RouterOS compared to standard Lua release. This example will show you how to get back 'print' command. Now you can include this custom function to other scripts and use this cool custom print function : You can also modify this function to write messages in RouterOS log.
Many users requested ability to work with files. Now you can do it without limitations. Create and write to file:. This example will show where to store and how to include your cool custom created functions into another scripts. Edit: If I really wanted to hide any malicious actions I could just reboot it which would clear the log anyway Last edited by Wyz4k on Thu Apr 13, am, edited 1 time in total.
Re: How to clear log Thu Apr 13, am But because the topic field is hardcoded I have to try and choose one which hopefully won't carry other traffic. Re: How to clear log Thu Apr 13, pm A nice feature request for ages that would help debugging a lot: The option to highlight words or rules in the log. Helps keeping visual track of what where happened when.
The option to then copy the highlighted parts from the log to paste in a txt doc or else. And last but not least, the option to search for specific text by a search box. Show your appreciation of this post by giving me Karma! Rudy R. Re: How to clear log Thu Apr 13, pm When you want to do nonstandard things with logging especially for debugging and monitoring I recommend to add an external syslog server.
Of course logging over the network means you won't get logs about network disconnections that would be forwarded over that same connection, and you also miss some of the startup messages that are sent before the network comes up, but on the other hand you can select the syslog software that you want and have the features that you like including storing all logs in a searchable "database" more powerful than you can ever imagine.
This way, the built-in logging system can be kept simple. I usually don't even log to disk, only to memory. When you accidentally enter the password where it asks for the username, it is logged and kept in a place where you cannot easily delete it. There should be an option to never log usernames on failed logon attempts. And maybe it should be possible to overwrite them in the memory and disk logs. Getting the most out of this forum. Re: How to clear log Thu Apr 13, pm Don't agree.
I am a small operator and still have almost Mikrotik routers. To setup and use syslog to a remote server for all these is ridiculous. Imagine a 10K of bigger operator The log is a great troubleshooting tool, even for CPE's And indeed, usually the logs are also needed just to find out shortly before and after network issues Many other vendors that in itself have less extended OS systems have a log that can be marked and or selected to copy I don't think this would be hard to acheive for MT?
Re: How to clear log Thu Apr 13, pm With so many routers it is even more apparent that you need to install a syslog server! You do not need a separate server for every router, they can all log to the same server. Re: How to clear log Thu Apr 13, pm It sounds you can find a problem for every solution! Maybe you need to do some calculation of the amount of data and compare that to the size of a standard diskdrive.
Re: How to clear log Thu Apr 13, pm I'm with pe1chi and the log clearing camp on this one. Basic on-box log management functionality should be brought up to par with equivalent products.
The other side of the coin: That said. Any organization of any size especially int the business of providing network services should have at least a syslog server and a SNMP based monitoring solution. Any decent syslog server will let you rotate logs to match the size of disk available.
If you can afford MikroTiks you can afford a hard drive to cram an awful lot of syslog onto. My MikroTik's are not chatty at all with default syslog settings so in reality you can probably go pick up a Raspberry Pi, a 16gb SD card, an Ethernet cable and some duct tape and tape it under someones desk and be at least twice as good at troubleshooting.
I can't tell you how many organizations I've been to that will complain to no end about how crappy their gear, network or life is but have 0 monitoring. Examples are the best so I'll tell one of many stories that sold me on monitoring. I'm sitting in a meeting when I worked in an enterprise environment with our systems guys and the boos.
I'm the network guy. The systems guy says "hey we need to upgrade the load balancers.
