Plugin: go.d.plugin Module: openldap
This collector monitors OpenLDAP metrics about connections, operations, referrals and more.
It gathers the metrics using the go-ldap module and the Monitor backend of OpenLDAP.
This collector is only supported on the following platforms:
This collector supports collecting metrics from multiple instances of this integration, including remote instances.
The collector cannot auto-detect OpenLDAP instances, because credential configuration is required.
The default configuration for this integration does not impose any limits on data collection.
The default configuration for this integration is not expected to impose a significant performance impact on the system.
Follow instructions from https://www.openldap.org/doc/admin24/monitoringslapd.html to activate monitoring interface.
The configuration file name for this integration is go.d/openldap.conf
.
You can edit the configuration file using the edit-config
script from the
Netdata config directory.
cd /etc/netdata 2>/dev/null || cd /opt/netdata/etc/netdata
sudo ./edit-config go.d/openldap.conf
The following options can be defined globally: update_every.
Name | Description | Default | Required |
---|---|---|---|
update_every | Data collection frequency. | 1 | no |
timeout | Timeout for establishing a connection and communication (reading and writing) in seconds. | 2 | no |
url | LDAP server URL. | ldap://127.0.0.1:389 | yes |
username | The distinguished name (DN) of the user authorized to view the monitor database. | yes | |
password | The password associated with the user identified by the DN. | yes | |
tls_skip_verify | Server certificate chain and hostname validation policy. Controls whether the client performs this check. | no | no |
tls_ca | Certification authority that the client uses when verifying the server’s certificates. | no | |
tls_cert | Client TLS certificate. | no | |
tls_key | Client TLS key. | no |
A basic example configuration.
jobs:
- name: local
url: ldap://localhost:389
username: cn=netdata,dc=example,dc=com
password: secret
Note: When you define multiple jobs, their names must be unique.
Collecting metrics from local and remote instances.
jobs:
- name: local
url: ldap://localhost:389
username: cn=netdata,dc=example,dc=com
password: secret
- name: remote
url: ldap://192.0.2.1:389
username: cn=netdata,dc=example,dc=com
password: secret
Metrics grouped by scope.
The scope defines the instance that the metric belongs to. An instance is uniquely identified by a set of labels.
These metrics refer to the entire monitored application.
This scope has no labels.
Metrics:
Metric | Dimensions | Unit |
---|---|---|
openldap.current_connections | active | connections |
openldap.connections | connections | connections/s |
openldap.traffic | sent | bytes/s |
openldap.entries | sent | entries/s |
openldap.referrals | sent | referrals/s |
openldap.operations | completed, initiated | operations/s |
openldap.operations_by_type | bind, search, unbind, add, delete, modify, compare | operations/s |
openldap.waiters | write, read | waiters/s |
There are no alerts configured by default for this integration.
Important: Debug mode is not supported for data collection jobs created via the UI using the Dyncfg feature.
To troubleshoot issues with the openldap
collector, run the go.d.plugin
with the debug option enabled. The output
should give you clues as to why the collector isn’t working.
Navigate to the plugins.d
directory, usually at /usr/libexec/netdata/plugins.d/
. If that’s not the case on
your system, open netdata.conf
and look for the plugins
setting under [directories]
.
cd /usr/libexec/netdata/plugins.d/
Switch to the netdata
user.
sudo -u netdata -s
Run the go.d.plugin
to debug the collector:
./go.d.plugin -d -m openldap
If you’re encountering problems with the openldap
collector, follow these steps to retrieve logs and identify potential issues:
Use the following command to view logs generated since the last Netdata service restart:
journalctl _SYSTEMD_INVOCATION_ID="$(systemctl show --value --property=InvocationID netdata)" --namespace=netdata --grep openldap
Locate the collector log file, typically at /var/log/netdata/collector.log
, and use grep
to filter for collector’s name:
grep openldap /var/log/netdata/collector.log
Note: This method shows logs from all restarts. Focus on the latest entries for troubleshooting current issues.
If your Netdata runs in a Docker container named “netdata” (replace if different), use this command:
docker logs netdata 2>&1 | grep openldap
