I am trying to increase my mongo log level without success:
MongoDB shell version: 2.6.10
connecting to: test
> use TreeDB
switched to db TreeDB
> db.setLogLevel(5,"query")
2018-01-23T12:11:28.221+0100 TypeError: Property 'setLogLevel' of object TreeDB is not a function
How to correctly use this function?
> db.setLogLevel
TreeDB.setLogLevel
db.help() does not output this function.
docs.mongodb references it here since 3.0: https://docs.mongodb.com/manual/reference/method/db.setLogLevel/
I am using ubuntu 16.04, mongoshell 2.6.10, mongo: 3.6.2 (via docker)
As explained in the comments, I have to install at least 3.0 version of mongoshell.
This should be done following https://docs.mongodb.com/manual/tutorial/install-mongodb-on-ubuntu/

In mongosh
% mongosh
Current Mongosh Log ID: 630639411fcf560da1e8d627
Connecting to: mongodb://127.0.0.1:27017/?directConnection=true&serverSelectionTimeoutMS=2000&appName=mongosh+1.5.4
Using MongoDB: 6.0.1
Using Mongosh: 1.5.4
I am getting the error
test> printjsononline({teste : 1})
ReferenceError: printjsononline is not defined
But it used to work in mongo tool, before it was upgraded to mongosh. What did that function? How to replace it? This is used by an emacs mode (http://github.com/own-pt/sensetion.el) that I need to use.
Most functions which are removed in new mongosh are provided by the mongosh-snippets package in Github.
load('mongonative.js');
load('mongoassert.js');
load('mongotypes.js');
Or write your own function:
if (typeof tojsononeline == 'undefined') {
function tojsononeline(x) {
return EJSON.stringify(x)
.replace(/\{"\$date":"(.{19,23}Z)"\}/g, "ISODate(\"$1\")")
.replace(/\{"\$oid":"(\w{24})"\}/g, "ObjectId(\"$1\")")
.replace(/\{"\$numberDecimal":"(.+?)"\}/g, "Decimal128(\"$1\")");
}
}
As mentioned in the Mongosh documentation:
mongosh supports a subset of the mongo shell methods.
Achieving feature parity between mongosh and the mongo shell is an ongoing
effort.
I don't think the support for printjsononline is added yet. However, you can try printjson method of mongosh, if it works the same.
Check this list to find all the methods supported by mongosh.
when I run any query containing $expr operation against Embedded Mongo I get the following error:
UncategorizedMongoDbException: Query failed with error code 2 and error message 'unknown top level operator: $expr' on server
The command runs fine against my local instance of mongo.
This is the version of embedded mongo I'm using: testCompile('de.flapdoodle.embed:de.flapdoodle.embed.mongo:2.1.1')
This is the query for reference:
Criteria.where("$expr").ne(Arrays.asList("$val.a", "$val.b"))
Found it.
flapdoodle was downloading a version of Mongodb that didn't have that feature by default.
You can override the default version by specifying the following in your
src/test/resources/application.properties
spring.mongodb.embedded.version=3.6.4
spring.mongodb.embedded.features=SYNC_DELAY,NO_HTTP_INTERFACE_ARG,ONLY_WITH_SSL
When i try to insert data on mongodb 3 through command line it's showing following error
use video;
switched to db video
db.movies.insertOne({ "title": "Jaws", "year": 1975, "imdb": "tt0073195" });
2018-03-26T12:42:42.233+0530 E QUERY TypeError: Property 'insertOne' of object video.movies is not a function at (shell):1:11`
but video db also not created
Please help me to rectify this problem.
MongoDB supports db.collection.insertOne() from version 3.2, please check your mongodb version by using the mongo shell command
db.version()
References:
insertOne
version
Try with db.movies.insert instead of db.movies.insertOne and check If it's working fine. If it's working then your mongo version is less than 3.2. If not then share your mongoDb console Screenshot.
Migrating Data from Tokumx To Percona Server For MonoDB
Step 1 :
This guide describes how to upgrade existing Percona TokuMX instance to Percona Server for MongoDB. The following JavaScript files are required to perform the upgrade:
• allDbStats.js
• tokumx_dump_indexes.js
• psmdb_restore_indexes.js
You can download those files from GitHub.
Step 2 :
Run the allDbStats.js script to record database state before migration:
$ mongo ./allDbStats.js > ~/allDbStats.before.out
Step 3 :
Perform a dump of the database:
$ mongodump --out /your/dump/path
Step 4 :
Perform a dump of the indexes:
$ ./tokumx_dump_indexes.js > /your/dump/path/tokumxIndexes.json
Step 5 :
Restore the collections without indexes using “--noIndexRestore” switch:
$ mongorestore --noIndexRestore /your/dump/path
Step 6 :
Restore the indexes (this may take a while). This step will remove clustering options to the collections before inserting.
$./psmdb_restore_indexes.js --eval "data='/your/dump/path/tokumxIndexes.json' "
Step 7 :
Run the allDbStats.js script to record database state after migration:
mongo ./allDbStats.js > ~/allDbStats.after.out
This is the guide i have found in the Migration from Tokumx to Percona server for mongodb. at step 6 when i try to restore indexes i get below mentioned error :
/mnt/tokumx-bkup/tokumxIndexes.json
2016-06-29T05:28:20.028+0000 E QUERY SyntaxError: Unexpected identifier

Any help will be welcomed.
Thanks
check the tokumxIndexes.json file. When tokumx_dump_indexes.js is run, the mongo shell parameter --quiet must be used or the resulting json will contain the shell preamble at the beginning.
And check the file using something like http://jsonlint.com/
Also if preamble is present delete these two lines from the tokumxIndexes.json file.
"MongoDB shell version: 3.0.11-1.6
connecting to: 127.0.0.1:27017/test"
and Run the script again.
and Run the script again
$./psmdb_restore_indexes.js --eval "data='/your/dump/path/tokumxIndexes.json' "
Now this script will start build Index Process.
I am running Debian with MongoDB shell version: 2.4.3
I run
use dbname
db.stats.find()
And it outputs the following
> db.stats.find()
Mon May 13 17:55:20.933 JavaScript execution failed: TypeError: Object function (scale){
return this.runCommand( { dbstats : 1 , scale : scale } );
} has no method 'find'
However running it on other collections works fine.
This mongo instance is being used with nodejs.
If you really created a collection named stats in your database dbname then I would advise you to rename it. In the shell the db object has a stats() method for looking at statistics of the database.
Meanwhile you can use slightly more complex syntax:
> db.getSiblingDB("dbname").getCollection("stats").find()
Fetched 0 record(s) in 4ms
Or if you are in dbname then:
> db.getCollection("stats").find()
I presume you want db.stats().
