Are you retired, jobless, won the lottery or did your wife leave you?

Looking for ways to supplement the income to get the wife a ticket to MCM Comic Con (she loves Misha Collins and he's a guest)

(not to mention moving costs due to landlord selling the place I'm renting )

Jack Yaz, I had to try this on my RT-AC86U.

It installed no problem. It even ran the initial tests, but there is nothing showing in the graphs yet (I'm assuming I need to let it run a while, no problem).

The only little niggle I see is that the Run Ping Test Now button doesn't respond. Almost, like it is clicking/clicked, if you know what I mean? Maybe this needs some time too?

Thanks again for another great script to be able to play with.

Edit: Oh, I'm running 384.11 Alpha 3, btw.

First data should be graphed within 5-10 minutes (due to data points in the rrd)

Ah yes...forgot that bug....wait 30s and the page will refresh automagically (I need to patch in the Loading.... bit)

Should be fixed, run u in the menu

EDIT: also run

connmon startup

after updating

Jack are the results posted to syslog and are the results printed on graphs in a message as per speedtest? Im not seeing either at present when I press Run ping test now button.

PS - what time do the tests run please?

No to both currently. Due to the 5 minute frequency I didn't want to flood syslog. Showing the last result in the UI I can do though

Graphs should get new data points every 5 minutes now

Hmmmm, shows in my syslog (until I get it filtered with Scribe syslog-ng that is).

I was referring to the ping jitter and line quality metrics

Ah, I see, my bad.

 

[Swistheater]

when i use connmon it tells me there is a lock file and will not open the menu, but when i type in the long way it opens the menu....

This is repeatable? I didn't notice this aspect.

Maybe you're just impatient? Or, it was running a test in the background as it does?

Oh, yeah!

I figured I just wanted a second opinion other than my own.

To be clear here, I did notice that myself on the first install.

But what I was asking here; is this repeatable 'on command' when using the connmon vs. /jffs/scripts/connmon commands?

As I said, I've used both but did not find this behavior, it seems consistent for me (and I made sure I was within the scheduled runs too).
