python benchrun.py -f testcases/* -t 1 2 4 -s "C:\mgdb\bin\mongosh.exe" --replset rs0 --port 27050

Error:

I also tried with mongo shell version 4.4.8, 3.4.24, they also do not work
Above cases just typical cases

Exactly what is requirement for this tool pls

Hello,

Use the 'mongo' shell for benchrun, not the new 'mongosh' shell. In the third example you used 'mongos' - that is for sharding, it is not a shell. It should work with 'mongo'.

Hello, I've installed mongo on my laptop and I don't have mongo as of 6.0 version. Here is the list of binaries I have :

ls /usr/bin | grep mongo
mongod
mongodump
mongoexport
mongofiles
mongoimport
mongorestore
mongos
mongosh
mongostat
mongotop

Can you tell me how do you get mongo command line ?

Thanks

Since 5.0, mongo shell is deprecated. Do you plan to change the implementation and use mongosh ?

Thanks, best regards

We have an internal ticket to replace the old mongo shell with mongosh in performance infrastructure. The legacy shell can be used for testing. You should be able to use the legacy shell from 5.0 with 6.0 if you want.

Hi @ghartnett, I've launched the benchmark on my local database started with a replica set and all works fine like you said.
When trying to run the benchmark in mongo atlas, I got the following error : Mixing ssl modes with a single replica set is disallowed

The main difference between the local server and the atlas one is basically the usage of ssl protocol. Have you encountered that before ? This error is thrown by benchRun. Doing a simple insert such as db.test0.insert({}) works fine!

By the way, do you have an ETA for the migration to mongosh ?

Thanks for your feedback.

Best regards,

Hi,

Got a response from mongodb support. FYI, benchRun is not designed to be run in mongo atlas.

Best regards
