März 2026 * * ![](https://www.servicenow.com/docs/portal-asset/ico-clock) 3 Minuten Lesedauer Agent Client Collector provides the following policies for Apache Kafka health monitoring. Policies come with the checks specified in the indicated table. Policies and checks are available for both Windows and Linux. {#kafka-checks-policies__table_y3r_2qd_2tb__entry__4} | Check | Description | Usage | Output | |-|-|-|-| | kafka.check-zookeeper-status | Raises a critical event if the hosted Kafka Zookeeper is down. | `commonchecks check-kafka-zk-status` \[flags\] Where the flags are: `-p, --port =` Zookeeper Port (default "2181"). Usage example: `commonchecks check-kafka-zk-status -p 2181` | Kafka Zookeeper Status OK: Kafka Zookeeper is Up! | | kafka.check-topic-replicas | Raises critical event if any topic has partitions with unknown replicas. | `commonchecks check-kafka-replicas ` \[flags\] Where the flags are: * `-p, --port =` Zookeeper Port (default "2181"). * `-d, --detailed` = Lists unknown replicas in each partition of a topic. * `-i, --include_list` = Comma seperated list to include topics (allows \* wild character) * `-e, --exclude_list` = Comma seperated list to exclude topics (allows \* wild character) {#kafka-checks-policies__ul_wtk_yhl_25b}Usage example: commonchecks check-kafka-replicas -H localhost -p 2181 -i "test\*" -e "accTopic,\*offsets" -d | \ has partitions with unknown replicas. Unknown replicas are: {"0":\["0"\],"1":\["0"\],"2":\["0"\]}. \ has partitions with unknown replicas. Unknown replicas are: {"0":\["0"\]}. | | kafka.check-topic-replication-factor | Raises critical event if replication factor of at least one topic is above or below provided replication factor param. | `commonchecks check-kafka-rf` \[flags\] Where the flags are: * `-p, --port =` Zookeeper Port (default "2181"). * `-d, --detailed` = Lists unknown replicas in each partition of a topic. * `-i, --include_list` = Comma separated list to include topics (allows \* wild character) * `-e, --exclude_list` = Comma separated list to exclude topics (allows \* wild character) * `-r, --replication factor` = Expected replication factor for a topic (default 1) {#kafka-checks-policies__ul_gcn_mcm_f5b} Examples: `commonchecks check-kafka-partitions -H localhost -p 2181 -r 2 -i "accMetrics,*Topic" -e "testTopic"` | TestTopic has replication factor 1, which is less than expected: 2. accMetrics has replication factor 1, which is less than expected: 2. | | kafka.check-topic-leader | Raises critical event if any topic has partitions with unknown leaders or unpreferred replica as leader. | `commonchecks check-kafka-leader` \[flags\] Where the flags are * `-p, --port` = Zookeeper Port (default "2181"). * `-d, --detailed` = A list of partitions in each topic with unknown leaders or unpreferred replicas. * `-i, --include_list` = Comma separated list to include topics (allows \* wild character) * `-e, --exclude_list` =Comma separated list to exclude topics (allows \* wild character) {#kafka-checks-policies__ul_bqh_gdm_f5b} Examples: `commonchecks check-kafka-leader -H localhost -p 2181 -d -e "*offsets"` | \ contains, partitions with unpreferred replica as leader.(partitions with unpreferred replicas are \[0\]). \ contains, partitions with unpreferred replica as leader.(partitions with unpreferred replicas are \[0\]). | | kafka.check-topic-partitions | Raises critical events if number of partitions for a topic is less the min_partitions param. | `commonchecks check-kafka-partitions [flags]` Where the flags are: * `-p, --port` = Zookeeper Port (default "2181"). * `-P, --min_partitions` = Minimum partitions for a topic (default 1). * `-i, --include_list` = Comma separated list to include topics (allows \* wild character) * `-e, --exclude_list` =Comma separated list to exclude topics (allows \* wild character) {#kafka-checks-policies__ul_q5g_xxd_2tb} | | | kafka.check-topic-partitions | Raises critical events if number of partitions for a topic is less the min_partitions param. | Usage example 1: `commonchecks check-kafka-partitions -H localhost -p 2181 -P 3` | \ has 1 partitions, expected at least 3. \ has 1 partitions, expected at least 3. \ has 1 partitions, expected at least 3. | | kafka.check-topic-partitions | Raises critical events if number of partitions for a topic is less the min_partitions param. | Usage example 2: commonchecks check-kafka-partitions -H localhost -p 2181 -P 3 -i "accMetrics,\*Topic" -e "testTopic" | \ has 1 partitions, expected at least 3. \ has 1 partitions, expected at least 3. | [Tabelle : 1.
