Ce que DumbMonit surveille

Apache Kafka and compatible brokers (Redpanda, Confluent): offline and under-replicated partitions, a missing controller, and the lag of the consumer groups.

  • Redpanda
  • Confluent Platform

Comment il se connecte

Ce qu'il faut

  • SASL/PLAINFor a SASL_SSL listener only: the password is accepted over TLS and never sent in clear text.

Aucun compte nécessaire.

Ports réseau à ouvrir

  • 9092/TCPKafka protocol (default port, plain or TLS), every broker is contacted
Étapes de mise en place: Give DumbMonit read-only access to Kafka

  1. Skip this step for a cluster without an authorizer. Otherwise give a dedicated principal read-only ACLs, from a host that can reach the brokers.

    kafka-acls.sh --bootstrap-server kafka.lan:9092 --add --allow-principal User:dumbmonit --operation Describe --cluster
kafka-acls.sh --bootstrap-server kafka.lan:9092 --add --allow-principal User:dumbmonit --operation Describe --topic '*'
kafka-acls.sh --bootstrap-server kafka.lan:9092 --add --allow-principal User:dumbmonit --operation Describe --group '*'

  2. In DumbMonit, enter the address of one broker, for example kafka.lan:9092: DumbMonit then contacts the other brokers at the addresses they advertise.

  3. Tick TLS if the listener is SSL or SASL_SSL, and enter the SASL/PLAIN user and password if the listener asks for them.

À savoir. Each broker must be reachable at the address it advertises (advertised.listeners): a broker DumbMonit cannot reach leaves the consumer lag incomplete. SASL/PLAIN is accepted only over TLS; SCRAM and Kerberos are not supported.
