Version Control for Splunk - "Restore has failed to complete successfully"

dshatto — Thu, 20 Aug 2020 21:10:41 GMT

@Garethan

When trying to test the app I get the following when trying to restore a dashboard

"Restore has failed to complete successfully in app search, object of type dashboard, with name <object name> "

I have confirmed that Im' using the Object URI/Name (not label).

In looking at the backup.log it is giving two warnings and an error:

WARNING i="splunkVCBackup" error/fatal messages in git stderroutput please review. stderrout="b'\n*** Please tell me who you are.\n\nRun\n\n git config --global user.email "you@example.com"\n git config --global user.name "Your Name"\n\nto set your account\'s default identity.\nOmit --global to set the identity only in this repository.\n\nfatal: empty ident name (for <splunk@<server.xx.xxx>) not allowed\nTo git@gitlab.com-<repo>/sharedteams/<project>/<repo>.git\n * [new tag] 2020-08-03_0746 -> 2020-08-03_0746\n'" ERROR i="splunkVCBackup" git failure occurred during runtime, not updating the epoch value.

Thanks for the direct email, looks like I don't get notified when someone mentions my application anymore 😞

I suspect the git command on this Linux server is refusing to do a checkout because the git configuration doesn't exist.

Something like:

git config --global user.email "you@example.com"

git config --global user.name "Your Name"

Run as the user running Splunk should fix it, although you might want to use a real email/name.

In the manual on github (or README.md in the app) I have mentioned under the "Can I use this application on Windows?":

And set the git global configuration git config --global user.name "John Doe" git config --global user.email johndoe@example.com

That's what I had to do on Windows to make the git clone/git checkout command work as expected...

Thanks for the response Gareth.

I checked the git config on the Linux box logged in as the Splunk user. The user.email and user.name are currently set.

Try setting debugMode to true and run it again and the logs should advise which command threw that error

When running requests.get() on the url output_mode=json is showing a 404

Re: Version Control for Splunk - "Restore has failed to complete successfully"

gjanders — Fri, 21 Aug 2020 01:06:33 GMT

If you can trim the https://<yourservername> part out, I'd just need to see the endpoint it is trying to hit.

Most likely the application name which defaults to SplunkVersionControl has been changed and a 404 will occur.

I have a setting called "remoteAppName" which is supposed to be the name of the app on the remote server, but I might have some code with the app name hardcoded somewhere.

Which server is throwing the 404? And what action is taken (or which log file) are you seeing it in?

Or I might have some context with more log entries..

The restore is being requested from a member of the SHC and is the server that is throwing the 404 error. The application and the git repo are on the deployment server. The SplunkVCRestore input is pointing to .58 which is one of the SHC members.

I thought that maybe it was because I wasn't trying to do the restore from .58 so I logged into that server but it still fails on the restore.

gjanders — Sat, 22 Aug 2020 02:07:37 GMT

So did the search app have a savedsearch named dds_git_test in that tag?

The code is saying it cannot find the saved search with that name in the backup...

Re: Version Control for Splunk - "Restore has failed to complete successfully"

dshatto — Mon, 24 Aug 2020 14:46:27 GMT

It is recording the name in the splunkversioncontrol_backup.log with the correct type (saved searches), app (search) and owner (dougs)

I am getting this info in the same log file: (NOTE: Items in bold are redacted)

I have confirmed the .gitconfig has the user.email and user.name but it continues to give a "Warning" in the log file.

Re: Version Control for Splunk - "Restore has failed to complete successfully"

gjanders — Mon, 24 Aug 2020 23:36:38 GMT

So if you login to the server where these logs are and run the below as the same username that is running Splunk:

cd /opt/{GIT repo}/vcbackup; git add -A; git commit -am "Updated by Splunk Version Control backup job splunkVCBackup"; git tag 2020-08-24_0832; git push origin master --tags

Note that you might have to edit a file or similar to make the git add/commit work, does that throw an error?

Because all the code does is run a shell that runs the above...so it should be identical to what you see as a command line user (assuming you are running as the same username that runs splunk)

Re: Version Control for Splunk - "Restore has failed to complete successfully"

dshatto — Tue, 25 Aug 2020 14:58:10 GMT

When I first cd to the git repo there is no vcbackup folder.

If I recall correctly from previous conversations you indicated to just let the Data Input created the temp directory. So I went into the backup data input and changed the temp directory to vcbackup1 and confirmed that it created the directory, which it did.

I then did cd to that directory and ran the commands you suggested. I had to use a different time for git tag because there was already one with that date/time. It didn't throw any errors on those commands.

It is still giving the Warning about the git config user.email and the error about the epoch value.

Re: Version Control for Splunk - "Restore has failed to complete successfully"

gjanders — Wed, 26 Aug 2020 00:34:45 GMT

I think something like this will work:

Go to the bin directory of the SplunkVersionControl app then:

run:

splunk cmd python

In the python window try:

from splunkversioncontrol_utility import runOSProcess, get_password
import logging
logger = logging.getLogger()
(output, stderrout, res) = runOSProcess("cd ~; echo `pwd` `whoami`; git config --list --global", logger, shell=True)

print(output)

print(stderrout)

I'll run some testing a bit later to confirm that should work but I believe that will print the git config

Re: Version Control for Splunk - "Restore has failed to complete successfully"

gjanders — Wed, 26 Aug 2020 01:25:00 GMT

With that runOSProcess you can execute any shell command so you could test a :

cd <your git directory>; echo `pwd`; touch file; git add file; git commit -m test; git push origin master

Or similar and see what happens 🙂

Re: Version Control for Splunk - "Restore has failed to complete successfully"

Perhaps run a

In that directory first

Re: Version Control for Splunk - "Restore has failed to complete successfully"

dshatto — Thu, 27 Aug 2020 14:10:46 GMT

The git pull worked fine and the commands ran fine after the pull as well.

One thing I missed was your response earlier about the python commands to print the .gitconfig but it's not working

Here is the config

user.email=<my_email>
user.name=<my_userid>
push.default=simple

Re: Version Control for Splunk - "Restore has failed to complete successfully"

gjanders — Fri, 28 Aug 2020 02:57:37 GMT

Something doesn't seem right here, so the git commands work fine?

Just to confirm the git commands are been run on the server that is running the actual backup/restore from git? Which might not be the one requesting the restore of the object...

Re: Version Control for Splunk - "Restore has failed to complete successfully"

dshatto — Tue, 01 Sep 2020 16:20:42 GMT

Correct, the Git commands were run on the deployment server which is connected to the Git repo

Re: Version Control for Splunk - "Restore has failed to complete successfully"

gjanders — Tue, 01 Sep 2020 23:38:28 GMT

So something is happening that is not obvious at all 😞

Is there an SSH key or something in use?

When you run this:

Go to the bin directory of the SplunkVersionControl app then:

run:

splunk cmd python

In the python window try:

print(output)

print(stderrout)

Which step or steps are failing? Clearly when splunk runs the commands it is getting a different result to when you run the commands in the shell...

Re: Version Control for Splunk - "Restore has failed to complete successfully"

dshatto — Wed, 02 Sep 2020 02:34:46 GMT

Ok, let's break this down a bit.

We are using an ssh key to connect to the repository.

I have gone to opt/splunk/etc/apps/splunkversioncontrol/bin and ran splunk cmd python

From there I successfully ran the commands you listed below. Here are the results.

>>> (output,stderrout, res) = runOSProcess("cd ~;echo 'pwd' 'whoami';git config --list --global",logger,shell=True)
>>> print(output)
pwd whoami
user.email=<my email address>
user.name=dshatto
push.default=simple

>>> print(stderrout)

I don't recall exactly where it was failing but I suspect that it was that I separating part of the command
