I don't mean to hijack but it would be nice to have a script reboot the router if CPU or RAM goes to over 80% - 100%
for 5 mins or so. I have a remote router that is at 90% ram from cacti but now I cannot ssh to it, web access
is failing so is the API.

Can you tell how i make a working script for my MikroTik RouterBOARD RB951G-2HnD my internet connection is a LTE Stick with newest software (hilink) and the internet is not as stable sometimes.. so sometimes it just stop working...

Can you show me a script for: pinging to a website (eg google.com) and if its not reachable it restarts the usb port after 1 min?

THanks for your helps mates!

:if ($"goodpings" = 0 ) do={

Hi Tom,

I'm brand new to scripting and have found your examples very helpful. I appreciate you sharing them.

Question: Are the quotes in the following line really supposed to be there?

:if ($"goodpings" = 0 ) do={

I couldn't get the script to work until I removed them.

Thanks in advance,

John

FYI - I am sometime planning to re-write a 2'nd newer version of my netwatch-script-reboot-on-ping-loss program.

:local continue true;
:local counter 0;
:local maxcounter 12;
:local sleepseconds 10;
:local goodpings 0;
:log error "Script will further test ping to WAN in $sleepseconds seconds and will continue for $maxcounter x $sleepseconds seconds.";
:while ($continue) do={
    :set counter ($counter + 1);
    :delay $sleepseconds;
    :if ([/ping 8.8.8.8 interval=1 count=1] =0) do={
        :log warning "Ping to WAN failed on attempt $counter of $maxcounter - Will try again in $sleepseconds seconds.";
    } else {
        :log warning "Ping to WAN succeeded on attempt $counter of $maxcounter - No Further testing needed and script will exit.";
        :set continue false;
        :set goodpings ($goodpings +1);
        };
    :if ($counter=$maxcounter) do={
        :set continue false;
        }
    }
:if ($goodpings = 0) do={
    :/system routerboard usb power-reset duration=5
    }

Hi Tom,

I like the idea of adding the option for a second IP address to ping against to make double sure failure of the primary IP address isn't causing a false WAN failure.

I'm using a stripped down (simplified) version of your original script along with Netwatch to restart an attached USB cellular modem when needed. It's been working really well.

Using the script has greatly reduced false triggers which used to occur whenever my cellular provider refreshes the USB modem's DHCP lease... usually daily. That refresh temporarily interrupts WAN access for about 30 to 60 seconds, so I have the script reboot after 2 minutes of unsuccessful pings spaced 10 seconds apart.

Here's the script I'm currently using:

Code: Select all

:local continue true;
:local counter 0;
:local maxcounter 12;
:local sleepseconds 10;
:local goodpings 0;
:log error "Script will further test ping to WAN in $sleepseconds seconds and will continue for $maxcounter x $sleepseconds seconds.";
:while ($continue) do={
    :set counter ($counter + 1);
    :delay $sleepseconds;
    :if ([/ping 8.8.8.8 interval=1 count=1] =0) do={
        :log warning "Ping to WAN failed on attempt $counter of $maxcounter - Will try again in $sleepseconds seconds.";
    } else {
        :log warning "Ping to WAN succeeded on attempt $counter of $maxcounter - No Further testing needed and script will exit.";
        :set continue false;
        :set goodpings ($goodpings +1);
        };
    :if ($counter=$maxcounter) do={
        :set continue false;
        }
    }
:if ($goodpings = 0) do={
    :/system routerboard usb power-reset duration=5
    }

Netwatch script executed on Down:

Code: Select all

log warning "Netwatch ping to WAN failed.";/system script run WANPing

Netwatch script executed on Up:

Code: Select all

/tool e-mail send to=xxxxxxxx@xxxxxxx.net subject="MikroTik Netwatch Ping Failure" body="MikroTik router Netwatch detected a ping to WAN failure and the WANPing script was executed.  Check router log for details.";log warning "Netwatch ping failure notification email sent."

Have a great day,

John

hello and thank you.
i get a message in log that is not enough permissions.
what permissions are need it just to reboot after 5 minutes?

Dear friend
I am really in need for that script, I have tried it but it seems that it's not working with me .

This is for you:

======================================================================
Here is the information:

First - I assume your Mikrotik router performing the test is IP address 192.168.61.9

Second - I assume the remote device you want your Mikrotik router to test to is 192.168.61.7

Here are the instructions:

#1 Winbox into your 192.168.61.9 Mikrotik

#2 Go to Tools - Netwatch

#3 If you have anything in there then remove it

#4 Click on the RED "+"

#5 On the Host tab.
Type in "192.168.61.7"
Interval should be "00:01:00"
Timeout should be "1000"

#6 click on the Down tab.
Paste in the entire line below:
log warning "Netwatch missed a ping to 192.168.61.7 - starting 5 minute timeout script" ; /system script run NetWatchBoot-192.168.61.7

Now push the Enter button (you want your curser on the bottom on a blank line)

What you typed in should look like this:

|-----------------------------------------------
|log warning "Netwatch missed a ping to
|192.168.61.7 - starting 5 minute timeout
|"script" ; /system script run NetWatchBoot-
|192.168.61.7
|
|
|------------------------------------------------
Note - You need to make sure you pushed the Enter button after the last line and hit the "APPLY" button.

**** At this point - you have finished part 1 of 2 things you need to do *****

#7 Go to System - Scripts

#8 If you have anything in there then remove it

#9 Click on the RED "+"

#10 In the name box, paste in the line below:

NetWatchBoot-192.168.61.7

#11 The owner should be "admin" and make sure every check box is checked.

#12 In the Source: box, paste in the following 3 lines:[/color]
:if ([/ping 192.0.2.254 interval=5 count=60] =0) do={
/system reboot
}


Now push the Enter button (you want your curser on the bottom on a blank line)

What you typed in should look like this:
|---------------------------------------------
|:if ([/ping 192.0.2.254 interval=5 count=60]
|=0) do={
|/system reboot
|}
|
|
|--------------------------------------------

Note - You need to make sure you pushed the Enter button after the last line and hit the "APPLY" button.

***** At this point - you have finished part 2 of 2 things you need to do - it is running now *****
INFORMATION - INFORMATION - INFORMATION -

The Netwatch you just configured (part 1 of 2) checks every minute to see if it can ping "192.168.61.7".
If it can ping "192.168.61.7" then the script will exit and auto run another test a minute later.

If the Netwatch script can not ping "192.168.61.7" then it will run the system-script you created (part 2 of 2).
The system-script will try every 60 seconds to ping "192.168.61.7" for five times.
If there is an answer to ping to "192.168.61.7" during this 5-minute period, then the system-script will exit.
If there are no answers to pings to "192.168.61.7" during the 5-minute period, then the Mikrotik router will reboot.

NOTE - NOTE - NOTE
Every time the Netwatch-script fails to ping "192.168.61.7" it will place a blue line in your Mikrotik log.
If you see many blue lines in your log file that look like
Netwatch missed a ping to 192.168.61.7 - starting 5 minute timeout script
Then you should check how good your connections are from your Mikrotik router to the remote 192.168.61.7 device

I hope this helps

Hi Tom,
I'm trying your script, but I get an error in the log like this: "could not run script Reboot-ping-failed: not enough permissions"
