Hello Mike,

It seems that the optical limits are not correct read out from Huawei S5720/S6720.

I suspect that they are read from SNMP?

Gr,

Bernd

Indeed, thanks for the super quick solving!

Derp, this also fixed now in r9756.

Tnx for debugging

see attachments.

Helllo Mike,

I did following, disabled "Convert Port DOM power sensors to dBm".

Patch observium with:

svn update

./discovery -u

./discovery.php -d -m ports,sensors -h er013.nikhef.****

./poller.php -h er013.nikhef.****

Then  RX and TX values are ok, but in mW instead of dBm.

Then i reenabled "Convert Port DOM power sensors to dBm".

and did:

./discovery.php -d -m ports,sensors -h er013.nikhef.****

./poller.php -h er013.nikhef.****

After that only TX is listed and in dBm. RX is removed.

I Hope you understand me now.

And I hope you use rolling (trunk) repository and have updated software before discovery (svn up).

you must rediscover sensors. This sensors should be already dBm (conversion not required).

if it doesn’t, add a new debug (with convert option enabled):

./discovery.php -d -m ports,sensors -h <device>

Hi Mike,

Thank for the quick solving.... in mw the values are now okay for RX/TX.

But if i switch on "Convert Port DOM power sensors to dBm" then RX dissapears. Only TX is in dbm visable.

Grtz,

Bernd.

Yah, I see. Fixed in r9751.
