LDAP and Redis Integration

Input and output integration overview

The LDAP plugin collects monitoring metrics from LDAP servers, including OpenLDAP and 389 Directory Server. This plugin is essential for tracking the performance and health of LDAP services, enabling administrators to gain insights into their directory operations.

The Redis plugin enables users to send metrics collected by Telegraf directly to Redis. This integration is ideal for applications that require robust time series data storage and analysis.

Integration details

LDAP

This plugin gathers metrics from LDAP servers’ monitoring backend, specifically from the cn=Monitor entries. It supports two prominent LDAP implementations: OpenLDAP and 389 Directory Server (389ds). With a focus on collecting various operational metrics, the LDAP plugin enables administrators to monitor performance, connection status, and server health in real-time, which is vital for maintaining robust directory services. By allowing customizable connection parameters and security configurations, such as TLS support, the plugin ensures compliance with best practices for security and performance. Metrics gathered can be instrumental in identifying trends, optimizing server configurations, and enforcing service-level agreements with stakeholders.

Redis

The Redis Telegraf plugin is designed for writing metrics to RedisTimeSeries, a specialized Redis database module for time series data. This plugin facilitates the integration of Telegraf with RedisTimeSeries, allowing for the efficient storage and retrieval of timestamped data. With RedisTimeSeries, users can take advantage of enhanced capabilities for managing time series data, including aggregated views and range queries. The plugin offers various configuration options to enable the flexibility needed to connect securely to your Redis database, including support for Authentication, Timeouts, data type conversions, and TLS configurations. The underlying technology leverages Redis’ efficiency and scalability, making it an excellent choice for high-volume metric environments, where real-time processing is essential.

Configuration

LDAP

[[inputs.ldap]]
  ## Server to monitor
  ## The scheme determines the mode to use for connection with
  ##    ldap://...      -- unencrypted (non-TLS) connection
  ##    ldaps://...     -- TLS connection
  ##    starttls://...  --  StartTLS connection
  ## If no port is given, the default ports, 389 for ldap and starttls and
  ## 636 for ldaps, are used.
  server = "ldap://localhost"

  ## Server dialect, can be "openldap" or "389ds"
  # dialect = "openldap"

  # DN and password to bind with
  ## If bind_dn is empty an anonymous bind is performed.
  bind_dn = ""
  bind_password = ""

  ## Reverse the field names constructed from the monitoring DN
  # reverse_field_names = false

  ## Optional TLS Config
  ## Set to true/false to enforce TLS being enabled/disabled. If not set,
  ## enable TLS only if any of the other options are specified.
  # tls_enable =
  ## Trusted root certificates for server
  # tls_ca = "/path/to/cafile"
  ## Used for TLS client certificate authentication
  # tls_cert = "/path/to/certfile"
  ## Used for TLS client certificate authentication
  # tls_key = "/path/to/keyfile"
  ## Password for the key file if it is encrypted
  # tls_key_pwd = ""
  ## Send the specified TLS server name via SNI
  # tls_server_name = "kubernetes.example.com"
  ## Minimal TLS version to accept by the client
  # tls_min_version = "TLS12"
  ## List of ciphers to accept, by default all secure ciphers will be accepted
  ## See https://pkg.go.dev/crypto/tls#pkg-constants for supported values.
  ## Use "all", "secure" and "insecure" to add all support ciphers, secure
  ## suites or insecure suites respectively.
  # tls_cipher_suites = ["secure"]
  ## Renegotiation method, "never", "once" or "freely"
  # tls_renegotiation_method = "never"
  ## Use TLS but skip chain & host verification
  # insecure_skip_verify = false

Redis

[[outputs.redistimeseries]]
  ## The address of the RedisTimeSeries server.
  address = "127.0.0.1:6379"

  ## Redis ACL credentials
  # username = ""
  # password = ""
  # database = 0

  ## Timeout for operations such as ping or sending metrics
  # timeout = "10s"

  ## Enable attempt to convert string fields to numeric values
  ## If "false" or in case the string value cannot be converted the string
  ## field will be dropped.
  # convert_string_fields = true

  ## Optional TLS Config
  # tls_ca = "/etc/telegraf/ca.pem"
  # tls_cert = "/etc/telegraf/cert.pem"
  # tls_key = "/etc/telegraf/key.pem"
  # insecure_skip_verify = false

Input and output integration examples

LDAP

1. Monitoring Directory Performance: Use the LDAP Telegraf plugin to continuously track and analyze the number of operations completed, initiated connections, and server response times. By visualizing this data over time, administrators can identify performance bottlenecks in directory services, enabling proactive optimization.

2. Alerting on Security Events: Integrate the plugin with an alerting system to notify administrators when certain metrics, such as bind_security_errors or unauth_binds, exceed predefined thresholds. This setup can enhance security monitoring by providing real-time insights into potential unauthorized access attempts.

3. Capacity Planning: Leverage the metrics collected by the LDAP plugin to perform capacity planning. Analyze connection trends, maximum threads in use, and operational statistics to forecast future resource needs, ensuring the LDAP server can handle expected peak loads without degrading performance.

4. Compliance and Auditing: Use the operational metrics obtained via this plugin to assist in compliance audits. By regularly checking metrics like anonymous_binds and security_errors, organizations can ensure that their directory services adhere to security policies and regulatory requirements.

Redis

1. Monitoring IoT Sensor Data: Utilize the Redis Telegraf plugin to collect and store data from IoT sensors in real-time. By connecting the plugin to a RedisTimeSeries database, users can analyze trends in temperature, humidity, or other environmental factors. The ability to query historical sensor data efficiently will aid in predictive maintenance and help in resource management.

2. Financial Market Data Aggregation: Employ this plugin to track and store time-sensitive financial data from various sources. By sending metrics to Redis, financial institutions can aggregate and analyze market trends or price changes over time, providing them with actionable insights derived from reliable time series analytics.

3. Application Performance Monitoring (APM): Implement the Redis plugin for gathering application performance metrics such as response times and CPU usage. Users can visualize their application’s performance over time with RedisTimeSeries, allowing them to identify bottlenecks and optimize resource allocation swiftly.

4. Energy Consumption Tracking: Leverage this plugin to monitor energy usage in buildings over time. By integrating with smart meters and sending data to RedisTimeSeries, municipalities or enterprises can analyze energy consumption patterns, helping to implement energy-saving measures and sustainability practices.
