I had the same problem using Oracle exporter 0.5.1 or 0.5.2 with OS version centos7.9 |
Same here: Oracle exporter 0.6.0
|
I have the same problem, too.
|
Seems this one might be solved by #460 |
@HansK-p The latest one is still 0.6.0 on Apr 6th, this commit was merged (Jul 29th) but not released, any update further? |
We have had no issues after we took the patched version into use some months ago. |
Thanks @HansK-p , may I know where/how I could get the patched version? |
I'm not very good with this, so my approach is probably not ideal. I cloned the repo, checked out v0.6.0, probably applied the small change manually based on #460, created the docker image and pushed it to our own container registry. This might work: git clone https://github.com/iamseth/oracledb_exporter.git cd oracledb_exporter/ git checkout 0.6.0 vi collector/collector.go # apply PR changes manually docker build --build-arg BASE_IMAGE=scratch --build-arg VERSION=0.6.0 --build-arg ORACLE_VERSION=19.14 -t oracledb_exporter:0.6.0-patched Be aware that I haven't double check if the information above is correct, but at least I tried a docker build and it didn't fail. I have not tried to create oracledb_exporter binaries, only containers. |
We are running the exporter in VM, the docker version may not help, but thanks a lot for the details, I will open an issue for this. |
same issue |
