I am hoping some one can help get this correct.

Here is the desired end result. I want to be able to run a script (manually) where my CRS109 runs a bandwidth test and then saves the results to a file. I want the test to run only 10 seconds.

This line of code works from the terminal screen and running a script from the terminal screen:

Code: Select all

/tool bandwidth-test $target duration=10s direction=both local-udp-tx-size=1000 protocol=udp remote-udp-tx-size=1000 user=$user pass=$pass

I am sure everyone has seen that code run. I get the results:

Code: Select all


     status: completetd

  duration: 10s

tx-current: 0bps

.......(and so on)

What I would like here is to take all of those values, and dump them into a text file. Creating a test script, I have been able to use

Code: Select all

/file set $filename contents=$data

and have created just junk data into a file. So I know how to put data into a file, and I can run a test to get the data. Where I am having issues right now is getting the data to dump into the file.

Thank you in advance for your help.

An update to this. I tried the following:

Code: Select all

/file set report.txt contents=(/tool bandwidth-test $target duration=10s user=$user pass=$pass)

And what I get is "true" in the file. The file gets accessed and modified, but the only thing in it is "true". It also just spits it out. The test should take about 10 seconds, but this script is done in a fraction of a second.

You ever get anywhere with this? I'm pretty new to scripting so I've been trying to makes sense of other posts.

I did. I'm away from my router right now, but I will post how I got it to work tonight.

I was able to remote in.

Here is how I did it:

Create a script with this in it. I named this one "server0". Make sure to update the IP address of the test server. You can also make the test run longer than 15 seconds, but when I did this, i didn't want to bog anything down on the test server's end.

Upload total average $txta Mbps/s

}

Once the script is done, then create a scheduler with this:

/system script run server0

The end run for me, I had 3 different server scripts (server0, server1, server2) set up with 3 different schedulers. Each script went to a different test server so i could get a good idea if I was having issues with my ISP. By testing against 3 servers, i could see a pattern of just one server always reporting low, or if all 3 reported low, it was me.

The schedules were setup to start at 00:00, 03:40, and 07:20. Each one ran recurring every 11 hours. This let me drift through the day and get a good feel for when I was getting slow service and when it was solid.

When the script ran, it would save a *.txt file on the router that I could download later on. The report looks like this:

{router name}
apr/01/2018 07:10:00

Result : done testing
Server : xxx.xxx.xxx.xxx 

Upload burst speed 4.935 Mbps/s
Download burst speed 11.253 Mbps/s

Upload total average 5.302 Mbps/s
Download total average 11.404 Mbps/s

FYI, this is one of the reports I showed to my ISP to prove they were not giving me the speeds I was promised.

Hope this helps.

thank you for posting this! I already had a script that ran a BW test every 5 minutes, but i was then just using SNMP to "grab" the results (ie snmp traffic with short interval, and looking for the spike).

I can add this- for some of my mt scripts, one way to retrieve the value of a variable (or result from a script), if its a number (maybe integer only? not sure), is to have the script assign the value of the variableto a Simple Queue's name. And then with snmp you can pull the value of the simple queues name (and thus you can graph that script variable). I use this for graphing the number of active VPN sessions on a mt vpn server i have (or in another case, for snmp graphing the current number of "NAT connections open/tracked", via /ip fire connections print count) .
EDIT- i also have one of these setup to snmp graph the value of /ip neighbor count

below is script i wrote for that task. (i am going to modify your script to try to snmp graph the results of scheduled BW tests, i will post that if im successful in a few hours).

(i just have a single scheduler entry that runs every 5 minutes for this below):

code:
/queue simple set [find comment="SNMPget_vpnACTIVEconnections_Count_Holder"] name=[/ppp active print count-only]

or export:

/system scheduler
add interval=4m name=queueIPneighbor on-event=\
    "/queue simple set [find comment=\"SNMPget_vpnACTIVEconnections_Count_Holder\"] name=[/ppp active print count-only]" policy=\
    ftp,reboot,read,write,policy,test,password,sniff,sensitive,romon start-time=startup

you need to create a dumb simple queue to hold this value, you can set it to disabled=yes (then use /queue simple print OID to get its snmp oid to query)

EDIT 2- well that was quick and easy! Credit ofcourse to OP - vader7071 . i just deleted some lines and added a few, he did the heavy work!
You do need to create 2x disabled simple queues named:
bwTX
and
bwRX
(and then can use /queue simple print oid and grab the "name=" oid from each of the 2x queues, and plug that into your SNMP graphing tool, i use PRTG).
and ofcourse set the IP of your BW test server (IP , not dns). Im using his txcB / rxcB varables as the sites im using this on, are are many megabits in speed. so if you need kb or a lower measurement scale, you can modify the varables accordingly (or use the direct output from the bw-test run, ie the $txc but remove the "/1000" part)

Hi,

I came across this script, but it wasn't working for me in ROS 6.47, so I had to tweak it a bit before it worked.

:set filename "$year$month$day-$hour$min-report.txt"

:log info "Bandwidth-test start"

:set $rxcC ($rxcA - $rxcB)
:set $rxcB ($rxcB / 1000)
:set $rxc "$rxcB.$rxcC"

:set $rxtaA ($"rx-total-average" / 1000)
:set $rxtaB ($rxtaA / 1000 * 1000)
:set $rxtaC ($rxtaA - $rxtaB)

:set result $status

}

:log info "Bandwidth-test done"

/file print file=$filename
:delay 5
/file set $filename contents="$sysname

$datetime



Result : $result

Server : xxx.xxx.xxx.xxx



Upload burst speed $txc Mbps/s
Download burst speed $rxc Mbps/s

Upload total average $txta Mbps/s
Download total average $rxta Mbps/s"

:log info "Speed test results written to $filename"

For some reason I kept getting a "no such item" error when running the script manually, so adding the delay ultimately fixed it.
Sometimes the local and remote udp-tx-size doesn't work, so you can remove those if necessary.
Anyway, hope this helps someone.

Cheers

From which server are you pulling test file?
How does it work?
