MongoDB
MongoDB is a document-oriented NoSQL database. CloudWisdom can be used to monitor your MongoDB’s performance.
Prerequisites
The Linux Agent must be setup before you proceed with the MongoDB integration.
Configure
Navigate to the collectors folder,
/opt/netuitive-agent/conf/collectors.Open the MongoDBCollector.conf file.
Change the enabled setting to
True.Replace the default host address and/or port number if necessary.
Save the configuration file, and restart the Linux Agent.
Tip
Due to the large number of metrics generated by MongoDB, you shouldn’t monitor more than one MongoDB host per agent.
Collector Options
Option | Default | Description |
|---|---|---|
enabled | FALSE | Enable collecting these metrics. |
host | 127.0.0.1:27017 | A single hostname(:port) to collect from. Overrides hosts. |
metrics_blacklist | “.databases.|.metrics.repl.executor.shuttingDown.|.storageEngine.|.writeBacksQueued.|.mem.supported.|.tcmallocformattedString.|^percent.*” | Regex list to match metrics to block. Mutually exclusive with metrics_whitelistoption. |
simple | TRUE | Set to “True” to only collect the same metrics as mongostat. |
byte_unit | Default numeric output(s). | |
cluster | If this node is part of a cluster, the collector will collect metrics on the cluster health. | |
collection_sample_rate | 1 | Only send stats for a consistent subset of collections. This is applied after collections are ignored via the ignore_collectionssetting. Sampling uses crc32 to ensure consistency across replicas. Value between 0 and 1. |
databases | .* | A regex of databases to gather metrics for. |
hosts | [‘localhost’] | An array of hostname(:port) elements to collect metrics from. Set an alias by prefixing “host:port” with alias@ |
ignore_collections | ‘^tmp.mr' | A regex of which collections to ignore. MapReduce temporary collections (tmp.mr.*)are ignored by default. |
metrics_whitelist | Regex list to match metrics to transmit. Mutually exclusive with metrics_blacklistoption. | |
network_timeout | Timeout for mongodb connection (in milliseconds). | |
passwd | Password for authenticated login (optional). | |
replica | False | Set to “True” to enable replica set logging. Reports health of individual nodes as well as basic aggregate stats. |
ssl | False | Set to “True” to enable SSL connections to the MongoDB server. |
translate_collections | False | Translate dot (.) to underscores (_) in collection names. |
user | User name for authenticated login (optional). | |
ssl_certfile | The certificate file used to identify the local connection against mongod. | |
ssl_keyfile | The private keyfile used to identify the local connection against mongod. | |
ssl_pem_passphrase | The password or passphrase for decrypting the private key in ssl_certfile or ssl_keyfile. Only necessary if the private key is encrypted. | |
ssl_cert_reqs | Specifies whether a certificate is required from the other side of the connection, and whether it will be validated if provided. | |
ssl_ca_certs | The ca_certs file contains a set of concatenated certification authority certificates, which are used to validate certificates passed from the other end of the connection. | |
ssl_crlfile | The path to a PEM or DER formatted certificate revocation list. | |
ssl_match_hostname | True | Enables hostname verification. |
auth_mechanism | SCRAM-SHA-1 | The default MongoDB authentication mechanism. |
