MongoDB Frequently Used Commands

uyarı

Direct intervention to data in production environments is never recommended. Before any operation or change to be made in production environments, the relevant steps must be tested in the test environment and a current backup of the system must be taken.

Connecting to MongoDB​

mongosh mongodb://localhost:25080 --authenticationDatabase "admin" -u "apinizer" -p

For All Operations After Connection​

You should switch to the correct database and work here:

use apinizerdb

General Commands​

# Show replicaset details
rs.status()

# Show users
db.getUsers()

# Show names and information of collections in the current database
db.getCollectionNames()
db.getCollectionInfos()

# View the size of any collection in MB
db.audit_event.stats().storageSize/1024/1024
db.user.find( { login: "admin" } );
 
db.db_to_api.find().pretty().limit(10)
 
#Full text search in API Proxy
db.api_proxy.ensureIndex(
    { "$**": "text" },
    { name: "TextIndex" }
);
 
#Performs a text search in a specific collection.
db.api_proxy.find(
    {
      $text: {
        $search: "XMLRESULTwithNS"
      }
    },{
        "name":1
    }
)
 
 #Search with criteria
db.api_proxy.find( {importedUrl: /.*kps.*/ })
 
#Search with multiple criteria
db.getCollection('api_proxy').find({$and: [{'routing.kpsSettings': { $exists: true }},{importedUrl: /.*kps.*/ }]})
 
#Regex usage
db.api_proxy.find({ "apiMethodList": { "$elemMatch": { "requestPolicyList": { "$elemMatch": { "name": { "$regex" : /^PolicyJwt3rdAuthentication/i } } } } } });
db.api_proxy.find({ "requestPolicyList": { "$elemMatch": { "name": { "$regex" : /^PolicyJwt3rdAuthentication/i } } } });
db.api_proxy.find({ "requestPolicyList": { "$elemMatch": { "_class": { "$regex" : /.*jwt.*/i } } } } , {"name":1,"requestPolicyList.name":1,"requestPolicyList._class":1});
 
#Search in all fields
db.api_proxy.find({ $where: function() {
  for (var key in this) {
    if (JSON.stringify(this[key]).indexOf("172.16.1.1") !== -1) {
      return true;
    }
  }
  return false;
}}, {_id: 0,name:1,projectId:1})
 
 
#Gets the count of logs up to the last 2 hours
mongosh mongodb://localhost:25080/apinizerdb --authenticationDatabase "admin" -u "apinizer" -p "password" --eval 'db.apinizer_log.find({"date":{"$lte": new Date((new Date().getTime() - (2 * 60 * 60 * 1000)))}}).count()'
 
#Searches for the expression <SEARCH_TERM> in all fields in all collections
db.getCollectionNames().forEach(function(collName) {
    var cursor = db[collName].find();
    while (cursor.hasNext()) {
        var doc = cursor.next();
        if (JSON.stringify(doc).includes("<SEARCH_TERM>")) {
            print("Found in " + collName);
            printjson(doc);
        }
    }
});

Searching Which Variable is Used in Which Methods of Which API Proxies​

not

Before running the function, you must switch to the correct database with the use apinizerdb command.

Update​

#Updating sub-element
db.api_proxy.update( {name :"KYS Yabanci AdSoyad Getir GW"}, {$set: {"routing.connectTimeout": "30"}} );
 
#Converting all "unwrapelement" objects' value to true in a proxy of Soap-2-Rest type (if editing is done in multiple arrays within 1 record, result returns as 1)
db.api_proxy.updateMany({relativePath:"/tarServis"},{$set:{"apiMethodList.$[].protocolTransformation.unwrapElement":true}});
 
#Adding object to sub-element (adds the relevant field to the second object of the array in the object)
db.api_proxy.update( {"relativePath":"/ydsSorgulamaServisi"}, {$push: {"requestPolicyList.1.unPasswordDecrypted": "false"}} );
 
 
#Setting admin user's password to "admin"
db.user.update({"login" : "admin"},{$set: { "password" : "$2a$10$Wv6i9IIdNzlxgDdaf13UdOl7uumVcG7zkSEKaOG4Xqn6IlLuwA13e"}});
 
#Unlocking admin user after lock

Replicaset Operations​

# Force replica to sync from master in replicaset system
rs.syncFrom("hostname:port");

Backup and Restore​

Taking Backup
sudo mongodump --host <IP_ADDRESS> --port=25080 --username=apinizer --password=<PASSWORD> --authenticationDatabase=admin --gzip --archive=/home/apinizer/apinizer-backup-2023-01-31--1.archive
Taking Backup Excluding Some Large Tables
sudo mongodump --host <IP_ADDRESS> --port 25080 --excludeCollection apinizer_log --excludeCollection audit_event -d apinizerdb --authenticationDatabase "admin" -u apinizer -p <PASSWORD> --gzip --archive=/home/apinizer/apinizer-backup-2023-01-31--1.archive
Restoring from Backup
sudo mongorestore --drop --host <IP_ADDRESS> --port 25080 -u apinizer -p <PASSWORD> --authenticationDatabase=admin --gzip --archive=/home/apinizer/apinizer-backup-2023-01-31--1.archive
Backing Up Single Collection
sudo mongodump --host <IP_ADDRESS> --port=25080 --authenticationDatabase "admin" -d apinizerdb -u apinizer -p <PASSWORD> --collection=<COLLECTION_NAME> --out=/home/apinizer/
Restoring from Single Collection Backup
sudo mongorestore --drop --host <IP_ADDRESS> --port 25080 --authenticationDatabase "admin" -d apinizerdb -u apinizer -p <PASSWORD> --collection=<COLLECTION_NAME> /home/apinizer/apinizerdb/<COLLECTION_NAME>.bson
Compressing with Gzip in Bulk Database Backups
not

Bulk database backups can be compressed with gzip, in this case you can create a proper archive using the command below and run the above command again.

gunzip < all-dbs-backup-2023-10-5--02.archive > all-dbs-backup-2023-10-5--02
Restoring Single Collection from Bulk Database Backup
mongorestore --host <IP_ADDRESS> --port 25080 --username apinizer --password <PASSWORD> --authenticationDatabase admin --drop --nsInclude 'apinizer-dev.environment_settings' --archive=all-dbs-backup-2023-10-5--02

Logs​

# Application logs
sudo tail -999f /var/log/mongodb/mongod.log

Recreating API Proxy in Apinizer and Accessing Elasticsearch Logs​

These commands are used to access Elasticsearch logs through the same API Proxy when an API Proxy is deleted and recreated or when export/import operations are performed.

# Store proxy document in a variable
doc = db.api_proxy.findOne({_id: ObjectId("WRONGPROXYID")})

# Set a new _id
doc._id = ObjectId("SHOULDBEPROXYID")

# Insert document with new _id
db.api_proxy.insert(doc)

# Delete document with old _id
db.api_proxy.remove({_id: ObjectId("WRONGPROXYID")})

# Required update for Apinizer
db.api_proxy_revision.update(
  { apiProxyId: "WRONGPROXYID" },
  { $set: { apiProxyId: "SHOULDBEPROXYID" } }
)

# Updating permissions
db.credential_allowed_api_proxy.updateMany(
  { apiProxyId: "WRONGPROXYID" },
  { $set: { apiProxyId: "SHOULDBEPROXYID" } }
)
