John,

I only had an SR1 for a short time in 2014. But plotSNR.exe will work with the SR1 if you can read out the
SNR automatically. This is certainly the case if you do MRTG monitoring. If not the old dogs stuff applies ...

But I can confirm that old dogs sometimes do learn new tricks. I recently learnt to use CAIRO graphics
in C and I translated a program I have written in Pascal 30 years ago. Old physicists always begin to
construct sundials. That's because they know that Kepler's principles will hold for thousands of years
even if they might not be around too long anymore. Here is a sundial for the front wall of my home.

It shows:
-True (local) Solar Time
-Italian hours (counted from sunset)
-Babylonian hours (counted from sunrise)
-Sunrise, sunset and length of the day in hours
-MEZ (corrected with analemma = graphical equation of time)

Once constructed it runs without Russian gas, French electricity or Internet access.

Best regards,
Ernst

P.S. I still have to learn to make your wonderful outage plots.

John,

in addition to my post above: IIRC all you need is being able to make some SNMP queries to your SR1. This means 2 things:

1) From the computer you want to do the outage SNR logging for plotSNR.exe you must have network access to the SR1.
2) On this very computer you must have some basic software to do these SNMP queries (PowerShell comes to my mind) .

If 2) is possible with PowerShell (I think so but have no SR1 to test that) then you need absolutely nothing but copy
my slightly adapted CMD script where the cmcs (Novra query) is replaced by a PowerShell command (SR1 query).

I'll have a look at that and maybe David can comment on the SNMP part (below stuff is used for an SNR query).

Target[SR1-snr]: 1.3.6.1.4.1.27928.101.1.1.4.4&1.3.6.1.4.1.27928.101.1.1.4.4:public@...

Cheers,
Ernst

I did purchase a TBS card many months ago when I thought my SR1 had failed.
However, I never installed it as the problem was a computer fault and the TBS
card remains in its box unused.

John,

You could get a TBS 5925 or 5927 second hand and run BDADataEx on that second
computer.

For the SR1, the connection details are:

OID: 1.3.6.1.4.1.27928.101.1.1.4.4
Management port: 192.168.0.195

That's all that's required for someone to write a small program to capture
every 5 seconds, in the format discussed earlier. Time to be in UTC (which
Windows and Linux use internally),

2022/10/08 10:49:25 10.8
2022/10/08 10:49:30 10.8
2022/10/08 10:49:35 10.8
2022/10/08 10:49:40 11.0
2022/10/08 10:49:45 10.7

David

David, John and All,

https://www.powershellgallery.com/packages/SNMP/1.0.0.1

All you probably need is install PowerShell Module SNMP
if you do not have that already (you must be Administrator!).

PS> Install-Module -name SNMP            

# If SNMP is installed this command should return the SNR of your SR1 at IP 192.168.1.254

PS> Get-SnmpData -IP 192.168.1.254 -Community public -OID 1.3.6.1.4.1.27928.101.1.1.4.4

This should also work in CMD as

CMD> PowerShell Get-SnmpData -IP 192.168.1.254 -Community public -OID 1.3.6.1.4.1.27928.101.1.1.4.4

Windows SR1 users that know what they do might test this but don't blame me.
If it works I promise to adapt my Novra SNR-collector CMD script for John's SR1.

Cheers,
Ernst

P.S. This means you get everything for free. If unsure goggle for "PowerShell SNMP" ...

Yes, that works as expected - see attached!

David,

thanks for this first test. I only have a Cisco SG200 switch that
understands SNMP on my LAN. But instead of reading all day
Cisco manuals and searching the Internet for the respective MIB
you could give me some more hand with your SR1. You had
to install the SNMP module as admin, now try as normal user:

PS> Get-Command -Module SNMP

This should answer with something like

Get-SnmpData
Invoke-SnmpWalk
Set-SnmpData

If so, I'm sure you will understand what that all means and try:

PS>Invoke-SnmpWalk -IP 192.168.0.195 -Community public -OID 1.3.6.1.4.1.27928.

This should give back all the stuff you can ask your SR1 for.

You certainly do not want to use the Set-SnmpData function
that (if available on an SR1) would use -Community private

Going back to our SNR problem could you please try this:

PS> (Get-SnmpData -IP 192.168.0.195 -Community public -OID 1.3.6.1.4.1.27928.101.1.1.4.4).Data

This should only give back one integer value 10 * SNR.

And finally:

PS> 0.1 * (Get-SnmpData -IP 192.168.0.195 -Community public -OID 1.3.6.1.4.1.27928.101.1.1.4.4).Data

PS> (Get-SnmpData -IP 192.168.0.195 -Community public -OID 1.3.6.1.4.1.27928.101.1.1.4.4).Data * 0.1

Or maybe:

PS> (Get-SnmpData -IP 192.168.0.195 -Community public -OID 1.3.6.1.4.1.27928.101.1.1.4.4).Data / 10

Or even (?):

PS> ((Get-SnmpData -IP 192.168.0.195 -Community public -OID 1.3.6.1.4.1.27928.101.1.1.4.4).Data) / 10


If this all works there is hope for John to record the next solar outage in spring 2023 ;-).

Cheers,
Ernst

P.S. Copy and paste from this web page to a PS> or CMD> console should work.

Here's the MIB [for SR1c_v1.05b257] attached, if that helps.

I'll see if I have time for the other tests later.

David,

here is the SNR script that should work. If you start it as is it will just note SNR 12.5 dB  no SNMP queries.

There is a DEBUG line:
set snmpsnr=echo 12.5

If you comment that out (on a PC you have installed the module) it should work with real SNMP queries.

Have fun,
Ernst

Ernst,

The script works correctly, just as expected, with live SNMP queries too.

I've updated the plotting program to use those UNIX seconds if they exist, but the hh:mm:ss must still have all three values, hh:mm alone is not accepted.

David
