SFDX creates enormous log files on my boot drive

[klivian]

Summary

SFDX creates many gigabytes of logfiles on my primary boot drive, causing the drive to run out of space

Steps To Reproduce:

**NB: This is not a repository-specific issue. Let me know if cli isn't the right repo for this

1. Use SFDX daily across multiple client projects on a Windows machine, averaging 10 hours a day :-(
2. Look at %USERPROFILE%/.sfdx folder
3. Check size of sfdx.log

Expected result

Should exist, but not be tens or hundreds of gigabytes in size

Actual result

This week it was 93.1gb in size. When I first discovered this issue on Jan 19th - 103.5gb

[ImJohnMDaniel]

Yeah, I saw the same thing. My log file was 333 GB and I deleted it just yesterday. Granted it had been approximately 2 months since I last purged that log file, but it was surprising to see it grow that much in such a short time.

[iowillhoit]

Yeesh, thanks for bringing this up. Do either of you have SFDX_LOG_LEVEL set (docs)? Having this set to debug or trace would drastically increase the number of logs in that file.

@klivian Are you saying that you got a 93.1GB log file in a single week? How long have you been working with sfdx on your machine?

@ImJohnMDaniel Are you also on Windows? For how long have you been aware of and occasionally clearing this file?

[ImJohnMDaniel]

I am on MacOS. I don't have SFDX_LOG_LEVEL set. I have been aware that the log file can get excessive for a year or more. I clear it out about once every 3 months or so. It routinely gets into the GB range quickly. Having said that, I have never seen it get that big before.

[iowillhoit]

Yea, 333GB is huge. Thanks for the additional info. I'll look into it.

[iowillhoit]

Hey @ImJohnMDaniel, could you run this to see if there is a single message that is especially noisy? This won't account for logs with small variations, but it's a good start to rule out something obvious. You'll need jq installed if you don't already.

@klivian, this might work for you if you are using WSL or GitBash on your machine. I've not tested it though

jq -c -r '. | { name, hostname, log, msg }' ~/.sfdx/sfdx.log | uniq -c | sort --reverse | head -n 20

[tprouvot]

Same issue here on Windows (more than 98GB), I tried to update sfdx (two versions) but nothing changed.

[klivian]

Just back to this after a few days off - no SFDX_LOG_LEVEL set, output from the jq command :-

5 {"name":"sfdx","hostname":"WINDOWS-N6U49BG","log":null,"msg":""}

[ImJohnMDaniel]

@iowillhoit, here is the jq output requested. Having said that, this was run on the current sfdx.log; not the large one that I deleted last week. I purged that from the recycle bin already

jq-review-of-imjohnmdaniel-sfdx.log

[iowillhoit]

Ok, thanks everyone. Was hoping we'd see something obvious. I will ask internally to see if I can find a large log file to look over.

[JonnyPower]

just came across this today as well - 360 gig log file. I purged it before analyzing (sorry) - will keep an eye open for how it grows over the next while and provide better information if it repeats.

[iowillhoit]

Hey @JonnyPower, no worries about deleting it. It's looking likely that we will be implementing a rotating log file to prevent these huge files in the future. Will post back here once it's released or if our plans change 👍

[uip-robot-zz]

This issue has been linked to a new work item: W-10745422

[klivian]

@iowillhoit - as part of the work on this, could I ask (if it isn't already planned) whether there could be a way to configure the storage location for the log file(s) ? I have ample space on my other drive but to the best of my knowledge, no way of telling SFDX to use it.

[iowillhoit]

@klivian it doesn't look like this is currently possible (source). This would be a much larger change since several commands rely on configs in this directory. However the defaults on the log rotation should be reasonable enough that you won't ever get close to 360GB again.

[bbarlowOpFocus]

I had setup SFDX on my current machine back in July. At the beginning of February my log file was over 800GB. I am glad to know that this is being addressed

[iowillhoit]

A change to implement a rotating file log has been released in today's release candidate (7.144.0). By default, the log file will rotate daily and we will keep two backups. These defaults can be modified with environment variables. More info in today's release notes. Please install the RC and let us know if you run into any issues. Thanks!
• Update with npm: npm install -g sfdx-cli@latest-rc
• Update with Installer: sfdx update stable-rc (run sfdx update stable to rollback)

[klivian]

@iowillhoit Been testing since 7.144.0 RC (now on 7.144.2 as of a few minutes ago) - log sizes dramatically reduced. I have sfdx.log at 3kb, sfdx.log.0 at 0kb and the new sf.log (in it's new directory) also at 0kb. Will continue to monitor until we go from RC to GA on this version

[iowillhoit]

That's great! Thank you for testing it out @klivian

[austin-convoy]

I've had the same issue pop up again, this time in the ~/.sf folder - again sf logs are taking up upwards of 200 GB before my storage maxes out. Should I file a separate issue?

[jverelst]

@iowillhoit I just updated SFDX in our azure pipeline, which runs every night to run all tests in our partialcopy org. I fear that this change has caused an issue for long-running commands that pass the 00:00h time mark:

You can see exactly at 00:00:00 errors are being generated, which result in the entire pipeline failing. This change in log-rotation seems to be the cause.

The pipeline in question usually runs about 5 hours, starting at 8pm GMT, finishing around 1am GMT. But now the pipeline immediately fails at 00:00.

[jverelst]

The script sf-run-testsuite has the following commands:

#!/bin/bash

# Clean up the testoutput directory and create it
if [ -e testoutput ]
then
  rm -rf testoutput/
fi
mkdir testoutput

# Disabled code-coverage, to improve performance of the entire test run
# EXTRAFLAGS="-c "
EXTRAFLAGS="-c"

# Upgrade the amount of results that can be returned, the default is 10.000, we make it 100.000
export SFDX_MAX_QUERY_LIMIT="100000"

# Instead of doing a 'RunLocalTests' (which will also run classes from unlocked packages),
# we make a list of all the testclasses in the src/ directory and only run those
ALLCLASSES=$(sfdx sfpowerkit:source:apextest:list --resultasstring --json -p src 2>/dev/null | jq -r .result)

# Run all tests
sfdx force:apex:test:run -w 300 -u $1 -n "$ALLCLASSES" -d testoutput/ -r json $EXTRAFLAGS > testoutput/output.json

# Retrieve the junit.xml file, to be displayed in azure
runid=$(cat testoutput/test-run-id.txt)
sfdx force:apex:test:report -u $1 -i $runid $EXTRAFLAGS -d testoutput/ -r junit

# Get the human-readable testoutput, and generate an MD file from it
sfdx force:apex:test:report -u $1 -i $runid -r human > testoutput/human.txt

# Make sure that the junit.xml file is valid, it may contain doublequotes due to a SFDX bug

[KacperAugustyniak]

So we have a similar problem, but with sf/sf.log file.
The whole file consists of lines like this:

{"name":"sf","hostname":"<redacted>","pid":15580,"level":60,"errno":-32,"code":"EPIPE","syscall":"write","msg":"","time":"2022-08-17T09:15:53.565Z","v":0}

And consumes all available space.

[austin-convoy]

Is there a follow-up to KacperAugustyniak's comment? We are also seeing this same bug take place in the .sf folder. Multiple log files taking up 30+ GB until the hard drive is out of space. Happens multiple times per week.

[peternhale]

@austin-convoy did you try the workaround mentioned in issue #1706?

set SFDX_LOG_ROTATION_PERIOD=1w

[KacperAugustyniak]

@austin-convoy We recently found out what was causing the enormous logs in our case.
We were having this problem when in GitLab runner a job was cancelled.
It turns out, when you cancel a job in GitLab runner it sends SIGKILL to the job, which apparently leaves orphan process if sfdx force:source:deploy already started, creating logs I mentioned above.
The solution was to never cancel from GitLab. Instead if we have co terminate a job, we do it from "Deployment status" page in Salesforce Setup or just let the job finish.

I hope this will help you find a solution to your problem.

[couturecraigj]

@peternhale will this help with .sf logs instead of .sfdx logs?

[peternhale]

@couturecraigj Not sure what you are asking?

[couturecraigj]

This

@couturecraigj Not sure what you are asking?

This was originally about an issue with .sfdx (%USERPROFILE%/.sfdx) log files. All our issues going forward are exploding in the .sf (%USERPROFILE%/.sf) log files.

[peternhale]

@couturecraigj thank you. The sf command is using the same log rotation logic as sfdx. Which version of sf are you using? Have you eliminated the possibility of orphaned processes as a source of log file growth?

[couturecraigj]

@peternhale I have not orphaned any processes that I can identify as I wait for all of them to complete

[dagreatbrendino]

I had this same issue. Was very confused as to how I was randomly running out of hard drive space. I've only been using SFDX to complete some trails for a week and it already ballooned to 33GB. There definitely seems to be some erratic logging going on here. There should at least be some config that can be used to set a max log file size.

[tehnrd]

FWIW, I just deleted a 335GB log file on MacOS. I never adjusted the log level from whatever the default is.

Unfortunately, I don't now if this started to slow in growth recently. I deleted the file and will monitor.

[jackexu]

Just deleted 328.2GB sfdx.log on MacOS without adjustment of log level or anything - just used it for a day or two.

sf no longer logs to the sfdx.log file. It logs to ~/.sf/sf-YYYY-MM-DD (see PR). Prior to that, it would log to sf.log.0, sf.log.1, sf.log.2. And prior to that, it logged to sfdx.log or sf.log.

It is likely you are getting the old Logger from the salesforcedx plugin. That is very old and should be uninstalled.
