+# mongodb
+
+Module monitor mongodb performance and health metrics
+
+**Requirements:**
+ * `python-pymongo` package v2.4+.
+
+You need to install it manually.
+
+
+Number of charts depends on mongodb version, storage engine and other features (replication):
+
+1. **Read requests**:
+ * query
+ * getmore (operation the cursor executes to get additional data from query)
+
+2. **Write requests**:
+ * insert
+ * delete
+ * update
+
+3. **Active clients**:
+ * readers (number of clients with read operations in progress or queued)
+ * writers (number of clients with write operations in progress or queued)
+
+4. **Journal transactions**:
+ * commits (count of transactions that have been written to the journal)
+
+5. **Data written to the journal**:
+ * volume (volume of data)
+
+6. **Background flush** (MMAPv1):
+ * average ms (average time taken by flushes to execute)
+ * last ms (time taken by the last flush)
+
+8. **Read tickets** (WiredTiger):
+ * in use (number of read tickets in use)
+ * available (number of available read tickets remaining)
+
+9. **Write tickets** (WiredTiger):
+ * in use (number of write tickets in use)
+ * available (number of available write tickets remaining)
+
+10. **Cursors**:
+ * opened (number of cursors currently opened by MongoDB for clients)
+ * timedOut (number of cursors that have timed)
+ * noTimeout (number of open cursors with timeout disabled)
+
+11. **Connections**:
+ * connected (number of clients currently connected to the database server)
+ * unused (number of unused connections available for new clients)
+
+12. **Memory usage metrics**:
+ * virtual
+ * resident (amount of memory used by the database process)
+ * mapped
+ * non mapped
+
+13. **Page faults**:
+ * page faults (number of times MongoDB had to request from disk)
+
+14. **Cache metrics** (WiredTiger):
+ * percentage of bytes currently in the cache (amount of space taken by cached data)
+ * percantage of tracked dirty bytes in the cache (amount of space taken by dirty data)
+
+15. **Pages evicted from cache** (WiredTiger):
+ * modified
+ * unmodified
+
+16. **Queued requests**:
+ * readers (number of read request currently queued)
+ * writers (number of write request currently queued)
+
+17. **Errors**:
+ * msg (number of message assertions raised)
+ * warning (number of warning assertions raised)
+ * regular (number of regular assertions raised)
+ * user (number of assertions corresponding to errors generated by users)
+
+18. **Storage metrics** (one chart for every database)
+ * dataSize (size of all documents + padding in the database)
+ * indexSize (size of all indexes in the database)
+ * storageSize (size of all extents in the database)
+
+19. **Documents in the database** (one chart for all databases)
+ * documents (number of objects in the database among all the collections)
+
+20. **tcmalloc metrics**
+ * central cache free
+ * current total thread cache
+ * pageheap free
+ * pageheap unmapped
+ * thread cache free
+ * transfer cache free
+ * heap size
+
+21. **Commands total/failed rate**
+ * count
+ * createIndex
+ * delete
+ * eval
+ * findAndModify
+ * insert
+
+22. **Locks metrics** (acquireCount metrics - number of times the lock was acquired in the specified mode)
+ * Global lock
+ * Database lock
+ * Collection lock
+ * Metadata lock
+ * oplog lock
+
+23. **Replica set members state**
+ * state
+
+24. **Oplog window**
+ * window (interval of time between the oldest and the latest entries in the oplog)
+
+25. **Replication lag**
+ * member (time when last entry from the oplog was applied for every member)
+
+26. **Replication set member heartbeat latency**
+ * member (time when last heartbeat was received from replica set member)
+
+### prerequisite
+Create a read-only user for the netdata in the admin database.
+
+1. Authenticate as the admin user.
+
+```
+use admin
+db.auth("admin", "<MONGODB_ADMIN_PASSWORD>")
+```
+
+2. Create a user.
+
+```
+# MongoDB 2.x.
+db.addUser("netdata", "<UNIQUE_PASSWORD>", true)
+
+# MongoDB 3.x or higher.
+db.createUser({
+ "user":"netdata",
+ "pwd": "<UNIQUE_PASSWORD>",
+ "roles" : [
+ {role: 'read', db: 'admin' },
+ {role: 'clusterMonitor', db: 'admin'},
+ {role: 'read', db: 'local' }
+ ]
+})
+```
+
+### configuration
+
+Sample:
+
+```yaml
+local:
+ name : 'local'
+ host : '127.0.0.1'
+ port : 27017
+ user : 'netdata'
+ pass : 'netdata'
+
+```
+
+If no configuration is given, module will attempt to connect to mongodb daemon on `127.0.0.1:27017` address

+# netdata python.d.plugin configuration for mongodb
+#
+# This file is in YaML format. Generally the format is:
+#
+# name: value
+#
+# There are 2 sections:
+# - global variables
+# - one or more JOBS
+#
+# JOBS allow you to collect values from multiple sources.
+# Each source will have its own set of charts.
+#
+# JOB parameters have to be indented (using spaces only, example below).
+
+# ----------------------------------------------------------------------
+# Global Variables
+# These variables set the defaults for all JOBs, however each JOB
+# may define its own, overriding the defaults.
+
+# update_every sets the default data collection frequency.
+# If unset, the python.d.plugin default is used.
+# update_every: 1
+
+# priority controls the order of charts at the netdata dashboard.
+# Lower numbers move the charts towards the top of the page.
+# If unset, the default for python.d.plugin is used.
+# priority: 60000
+
+# penalty indicates whether to apply penalty to update_every in case of failures.
+# Penalty will increase every 5 failed updates in a row. Maximum penalty is 10 minutes.
+# penalty: yes
+
+# autodetection_retry sets the job re-check interval in seconds.
+# The job is not deleted if check fails.
+# Attempts to start the job are made once every autodetection_retry.
+# This feature is disabled by default.
+# autodetection_retry: 0
+
+# ----------------------------------------------------------------------
+# JOBS (data collection sources)
+#
+# The default JOBS share the same *name*. JOBS with the same name
+# are mutually exclusive. Only one of them will be allowed running at
+# any time. This allows autodetection to try several alternatives and
+# pick the one that works.
+#
+# Any number of jobs is supported.
+#
+# All python.d.plugin JOBS (for all its modules) support a set of
+# predefined parameters. These are:
+#
+# job_name:
+# name: myname # the JOB's name as it will appear at the
+# # dashboard (by default is the job_name)
+# # JOBs sharing a name are mutually exclusive
+# update_every: 1 # the JOB's data collection frequency
+# priority: 60000 # the JOB's order on the dashboard
+# penalty: yes # the JOB's penalty
+# autodetection_retry: 0 # the JOB's re-check interval in seconds
+#
+# Additionally to the above, mongodb also supports the following:
+#
+# host: 'IP or HOSTNAME' # type <str> the host to connect to
+# port: PORT # type <int> the port to connect to
+#
+# in all cases, the following can also be set:
+#
+# user: 'username' # the mongodb username to use
+# pass: 'password' # the mongodb password to use
+#
+
+# ----------------------------------------------------------------------
+# to connect to the mongodb on localhost, without a password:
+# ----------------------------------------------------------------------
+# AUTO-DETECTION JOBS
+# only one of them will run (they have the same name)
+
+local:
+ name : 'local'
