If you have DCO and want the PUE dashboard amount shown by your SNMP monitor, especially DCE, here is a way to do it.

Dear Greg Sterling,

No, it does not depend on the browser or on the PC, etc. It looks like this is a feature from =SE= for me ☹️...

Hi spezialist, to avoid disclosure of sensitive information in attachments we have chosen to limit the visibility of certain attachments.

It's not Ed who has hidden the attachment. It's our policy to hide certain attachments. We're currently working on identifying and releasing attachments that don't reveal any sensitive information.

Hello,

At the time being we don't have a way to mark individual attachments as safe, thus we do it explicitly. A new upload will take a new ID and we will have to approve and whitelist it again, manually.

We will be working on making something more robust for future.

Hi Andrew

Thanks for the feedback.  Does the DCO PUE Dashboard work?  show a figure you're expecting?  Is DCE properly reporting the status of the DCO server?  If needed, please also check "Troubleshooting" in the attached DCO PUE in DCE V2.pdf

Let us know how you go

Cheers

PUE is working on DCO and DCE has values from yesterday, it appears to stop working at midnight. snmp.conf is correct and getPUE is a copy of the txt in the file so that should be correct. 

If i run the test script i get the result 

(23) Failed writing body
./test.sh: line 8: /1/ {print $2}: No such file or directory

ls dir is

-rwxr-xr-x.  1 root root   900 Mar 28 09:28 getPUE.sh

Andrew, 

Check the line in test.sh is a single line

pue=`/bin/curl -ks https://"$DCOip"/rest/pue-v1/instantPueData| awk -F":" '/1/ {print $2}'|awk -F"," '/1/ {print $1}' `

and not 2 lines as it show in the PDF

I'll update the doco to make this clear

Let me know how you go

Perfect, test script works and returns the correct value. What's also interesting is that at midnight last night we started receiving data again. 

Am i correct in assuming that  DCO only calculates the PuE once a day, the values for PuE are the same for the 24h period, or is this an issue with the way that I have this setup? 

Thanks for the assistance

Glad its working.  I know that the value only changes once per day and I assume its therefore only calculated once per day.

Hi Ed Tarento,

Glad to be able to search your valuable input here.

Is this method calculating historical PUE from DCE and DCO still applicable the latest DCE and DCO version?

Thanks,

Hi Fergus.  I'm not aware of any reason this solution should not still work.  Have you tried and failed with latest version/s?  If SE has changed DCO SNMP agent behaviour and/or PUE Dashboard API then that would affect this.  

Cheers

Hi Ed,

Thanks so much for the script. It helps us to solve a few headaches.

I have some DCO that work directly from your original script, maybe only need to edit the file via Webmin to make sure encoding follows Linux requirements. But for 3pcs DCOs I recently encountered, they only worked when I cut away the /1/ from awk commands i.e.

/bin/curl -ks https://"$DCOip"/rest/pue-v1/instantPueData| awk -F":" '{print $2}'|awk -F"," '{print $1}'

Is there any concern if I cut the /1/ away? Thanks a lot

Dear Gianluca Bertuletti,

From your question:

with snmpwalk i cannot find .1.3.6.1.4.1.26639.1.2.0

Have you made the necessary changes to the /etc/snmp/snmpd.conf file?

You have created the necessary /etc/snmp/getPUE.sh script as follows:

Have you restarted the snmpd service?

With respect.

For proper testing, you need, for example, to run this script with two parameters:

./getPUE.sh -g .1.3.6.1.4.1.26639.1.2.0

or

./getPUE.sh -n .1.3.6.1.4.1.26639.1.1.0

Try it.

Gianluca Bertuletti, you mean Notepad++ under Windows, and then you uploaded the file to the DCO server ? If yes, I did something very similar and it ended up not working.

I had to rewrite all the scripts by hand directly on the DCO server and using a text editor.

Ok, then try the following from DCO command line:

or from outside:

snmpwalk -v2c -cpublic <DCOip> .1.3.6.1.4.1.26639.1.2.0

I assume using SNMP v2 and public community string.

Dear Gianluca Bertuletti,

Regarding the test.sh file: make sure that you have exactly this line (spaces are important):

pue=`/bin/curl -ks https://"$DCOip"/rest/pue-v1/instantPueData| awk -F":" '/1/ {print $2}'|awk -F"," '/1/ {print $1}'`

This works fine for me:

[root@dco ~]# ./test.sh
localhost
-1.0

Regarding getPUE.sh file: this file is very simple and does not support snmpwalking of the full MIB tree (this is important). That is, snmpwalk ... <DCOip> enterprises, for example, will not work (you will not see what you would like). There are two ways to check the operation of this file:

[root@dco snmp]# snmpwalk -v2c -cpublic localhost enterprises.26639.1.2.0
SNMPv2-SMI::enterprises.26639.1.2.0 = STRING: "-1.0"

or

[root@dco snmp]# snmpget -v2c -cpublic localhost enterprises.26639.1.2.0
SNMPv2-SMI::enterprises.26639.1.2.0 = STRING: "-1.0"

For a DCE server, this is quite enough, since, for example, in its work it uses only snmpget requests, but not snmpwalk requests.

Hope this helps you.

With respect.

Dear Gianluca Bertuletti,

From your question:

for your experience, is it possible to have 2 decimals? 

now is 1.2 but in real 1.14

Unfortunately, the problem is on the DCE software side: for the Generic sensor type from Supplemental OIDs... menu it is impossible to specify the number of decimal places. That is, by default, only one decimal place (i.e. 1.0).

With respect.
