Adding upstream version 1.34.4. Signed-off-by: Daniel Baumann <daniel@debian.org>

# MongoDB Input Plugin
This plugin collects metrics about [MongoDB][mongodb] server instances by
running database commands.
> [!NOTE]
> This plugin supports all versions marked as supported in the
> [MongoDB Software Lifecycle Schedules][lifecycles].
⭐ Telegraf v0.1.5
🏷️ datastore
💻 all
[mongodb]: https://www.mongodb.com
[lifecycles]: https://www.mongodb.com/support-policy/lifecycles
## Global configuration options <!-- @/docs/includes/plugin_config.md -->
In addition to the plugin-specific configuration settings, plugins support
additional global and plugin configuration settings. These settings are used to
modify metrics, tags, and field or create aliases and configure ordering, etc.
See the [CONFIGURATION.md][CONFIGURATION.md] for more details.
[CONFIGURATION.md]: ../../../docs/CONFIGURATION.md#plugins
## Configuration
```toml @sample.conf
# Read metrics from one or many MongoDB servers
[[inputs.mongodb]]
## An array of URLs of the form:
## "mongodb://" [user ":" pass "@"] host [ ":" port]
## For example:
## mongodb://user:auth_key@10.10.3.30:27017,
## mongodb://10.10.3.33:18832,
##
## If connecting to a cluster, users must include the "?connect=direct" in
## the URL to ensure that the connection goes directly to the specified node
## and not have all connections passed to the master node.
servers = ["mongodb://127.0.0.1:27017/?connect=direct"]
## When true, collect cluster status.
## Note that the query that counts jumbo chunks triggers a COLLSCAN, which
## may have an impact on performance.
# gather_cluster_status = true
## When true, collect per database stats
# gather_perdb_stats = false
## When true, collect per collection stats
# gather_col_stats = false
## When true, collect usage statistics for each collection
## (insert, update, queries, remove, getmore, commands etc...).
# gather_top_stat = false
## List of db where collections stats are collected
## If empty, all db are concerned
# col_stats_dbs = ["local"]
## Optional TLS Config
# tls_ca = "/etc/telegraf/ca.pem"
# tls_cert = "/etc/telegraf/cert.pem"
# tls_key = "/etc/telegraf/key.pem"
## Use TLS but skip chain & host verification
# insecure_skip_verify = false
## Specifies plugin behavior regarding disconnected servers
## Available choices :
## - error: telegraf will return an error on startup if one the servers is unreachable
## - skip: telegraf will skip unreachable servers on both startup and gather
# disconnected_servers_behavior = "error"
```
### Permissions
If your MongoDB instance has access control enabled you will need to connect
as a user with sufficient rights.
With MongoDB 3.4 and higher, the `clusterMonitor` role can be used. In
version 3.2 you may also need these additional permissions:
```shell
> db.grantRolesToUser("user", [{role: "read", actions: "find", db: "local"}])
```
If the user is missing required privileges you may see an error in the
Telegraf logs similar to:
```shell
Error in input [mongodb]: not authorized on admin to execute command { serverStatus: 1, recordStats: 0 }
```
Some permission related errors are logged at debug level, you can check these
messages by setting `debug = true` in the agent section of the configuration or
by running Telegraf with the `--debug` argument.
