Last week v9.1.2 has been released. (6 nov 2023, I think it was)

After installing this version on my test instance (v9.1.1) everytyhing seems to work again including sendemail - no issues found. Great! 👍

After installing this version several days later on our production instance (9.1.0.2) also sendemail was working fine again. Great! 👍

NB. after that I was also able to fix all other issues on our production instance as mentioned before in this post, like: kvstore, secure gateway etc Great! 👍

Many thanks to support- and development team. I am now happy splunking again! 👍👍 😀

I hereby close this post.

I had the same issue with sending emails. I was able to resolve it by replacing the sendemail.py file in $SPLUNKetc\apps\search\bin, with an older version of sendemail.py. I still have the issue with endless loading on settings pages. How were you able to resolve this?

Did you upgrade to v9.1.2 already?  If so, I suggest you create a ticket at support.

The replacing was a temp work-around solution for us from v9.1.0.2.

On our test server I was curious if this work-around would still work on v9.1.1 - It did not !
So I decide to wait for the release of v9.1.2. 

After the release I first tested on our test server and had no problem any more with sending email. 
After some days we upgraded to V9.1.2 on our production machine.

Nb. Both our servers are running Windows 2019, and now both are on Splunk Enterprise v9.1.2 without problems so far.

Did you ever get a resolution? @apietersen ? Upgraded to 9.1.1 from 9.0.5 and saw that email alerts ceased.  I'm getting a similar message to you

response from support / development: (last week) and now testing,
worked and looks good sofar

temporary workaround:

--=-=--=-=-=-==-=-sendmail.py-=--=-=-=-=--
Do you have a test instance to check the one parameter?

We got an update from the developer team, to check the below parameter,
open the file SPLUNK_HOME/etc/apps/search/bin/sendemail.py
and you would find (approx line number 1571):

clear_password = cli_common.decrypt(encrypted_password, setEnv=True)
The setEnv flag needs to be modified from True to False, restart Splunk, and then check if the problem is resolved.

Note: Try with your test instance.

As the setEnv flag needs to be modified from True to False will be considered a temporary workaround for this issue. In the next release version 9.1.2, It will be fixed completely.

-=-=-=-=-=---=-icon-=-=-=-=--=

Additionally, the "loading" icon got stuck issue also will be fixed in version 9.1.2.

this worked - thanks.  lol I was looking for the differences between the previous versions of sendemail.  I was hoping that 9.1.2 would have gotten deployed sooner than later, but this will work until then.

Looking back:
v9.0.4.x no issues noticed
v9.0.5.x noticed KVStore issues 
v9.1.0.1 noticed all sort of issue including not working 'sendemail'  (upgraded as I had hoped/assumed to be fixed)
v9.1.0.2 still the same issues + new strange behaviour : only reading 3 columns from any csv file (upgraded as I hoped/assumed to be fixed)

Nb. Have a zoom meeting with Splunk support later this afternoon

thanks

After the upgrade to v9.1.0.2, last weekend - hoping and assuming some issues were adressed and fixed, as noted in this post, now another issue arised, which make our production-instance even more unreliable.

When using an siimple '| inputlookup email.csv' search it only show 3 columns !  On our fresh build test-server with instance v91.0.2 the same serahc produce the correct number of columns.

Has somebody experinced this same issue or have a glue why or have a tip. Or what do I miss here?

By the way. the sendemail did not work either after upgrade to v91.0.2, after restoring an sendemail.py file from backup v9.0.4 (as I described in this post  earlier sendemail was working again, for now. But what is next! 😞 

Nb. Sorry, I really think Splunk should pay more attention to testing and quality control before releasing new versions. 

thanks

Update:

SORRY, AT THE MOMENT NOT MUCH HAPPY SPLUNKING HERE

WE RUN A 2nd Splunk Enterprise server (FOR TEST/DEV etc) and most issue mentioned below shows on both machines….

Nb. A week before we upgraded our production machine we installed v9.0.1 on our test-server and we only noticed point 5 and 6 but were not alarmed by the things that would come later after we decided to go forward. It came to our attention after we did not see any Alerts and other emails were send.

After upgrade to v9.1.0.1 Splunk Enterprise, (single instance), last weekend (15 Juli 2023) + changing admin password as was suggested by Assist (which throws an error today / now !?)

Hi

based on that kvstore/mongodb message I suspect that mongoldb is not running? You could check it's status by 

splunk show kvstore-status --verbose

If it's not up and running you you'd found there reason from $SPLUNK_HOME/var/log/splunk/mongod.log  

Probably most common reason for "not running kvstore/mongod" is expired TLS certificate.

Hi isoutamo

I ran the kwstore diag, as admin: 
apietersen_0-1690006566891.png

  • not sure if this is TLS related?
  • also do not understand why I should have TLS enabled to acces to something running on the same single server/Splunk Enterprise instance?
  • where can I disable this in conf file?
  • or how to renwe cert??



thanks

  • Where and what can I change to get it working again or ignore these TLS SSL and/expired messages?
  • Where to renew these "indoor"  TLS certs  (self-signed cert I assume and hope) ?

As it said your tls/ssl cert has expired you need to renew it. 
If you are using Splunk’s default certs (you shouldn’t), just remove/rename old certificate file and restart splunk. That will generate a new one. If you are using official from some cert authority or your own, then you must get a new from there and replace current with that.

You could check that e.g. with command 

openssl x509 -in mycert.pem -text -noout

This told the validity and who has guaranteed it.
