      DESCRIPTION

      This command is used to set up email alerts on a cluster. Couchbase provides alerts for various issues that may arise in the cluster where it is recommended that the cluster administrator take action to ensure that applications continue to function properly. When setting up email alerts administrator can decide who gets alert emails and which alerts are sent.

      OPTIONS

      -c
      --cluster

      Specifies the hostname of a node in the cluster. See the HOST FORMATS section for more information on specifying a hostname.

      -u
      --username <username>

      Specifies the username of the user executing the command. If you do not have a user account with permission to execute the command then it will fail with an unauthorized error.

      -p
      --password <password>

      Specifies the password of the user executing the command. If you do not have a user account with permission to execute the command then it will fail with an unauthorized error. If this argument is specified, but no password is given then the command will prompt the user for a password through non-echoed stdin. You may also specify your password by using the environment variable CB_REST_PASSWORD.

      --enable-email-alert <num>

      Enables email alerts on this cluster. Set this option to "1" to enable alerts or "0" to disable alerts. This parameter is required.

      --email-recipients <email_list>

      A comma separated list of users to email when an alert is raised in the server.

      --email-sender <email>

      If email alerts an enabled then this option will set the sender email address.

      --email-user <user>

      The email server username for the sender email address. This field is required if the email address provided requires authentication.

      --email-password <password>

      The email server password for the sender email address. This field is required if the email address provided requires authentication.

      --email-host <host>

      The email server hostname that hosts the email address specified by the --sender-email option.

      --email-port <port>

      The email server port number of the server that hosts the email address specified by the --sender-email option.

      --enable-email-encrypt <num>

      Enables SSL encryption when connecting to the email server. Set this option to "1" to enable encryption or "0" to disable encryption. If this option is not set then encryption will be disabled.

      --alert-auto-failover-node

      Specifies that an email alert should be sent when a node is automatically failed over.

      --alert-auto-failover-max-reached

      Specifies that an email alert should be sent when the maximum amount of auto-failovers is reached.

      --alert-auto-failover-node-down

      Specifies that an email alert should be sent when auto-failover could not be completed because another node in the cluster was already down.

      --alert-auto-failover-cluster-small

      Specifies that an email alert should be sent when auto-failover could not be completed because the cluster is too small.

      --alert-auto-failover-disable

      Specifies that an email alert should be sent when auto-failover could not be completed because auto-failover is disabled on this cluster.

      --alert-ip-changed

      Specifies that an email alert should be sent when the IP address on a node in the cluster changes.

      --alert-disk-space

      Specifies that an email alert should be sent when the disk usage on a node in the cluster reaches 90% of the available disk space.

      --alert-meta-overhead

      Specifies that an email alert should be sent when the metadata overhead on the data service is more than 50%.

      --alert-meta-oom

      Specifies that an email alert should be sent when all of the memory in the cache for a bucket is used by metadata. If this condition is hit the bucket will be unusable until more memory is added to the bucket cache.

      --alert-write-failed

      Specifies that an email alert should be sent when writing data to disk on the data service has failed.

      --alert-audit-msg-dropped

      Specifies that an email alert should be sent when writing event to audit log fails.

      --alert-indexer-max-ram

      Specifies that an email alert should be sent when the memory usage for the indexer service on a specific node exceeds the per node memory usage limit. This warning is only shown for if the index storage type is Memory Optimized Indexes (MOI).

      --alert-timestamp-drift-exceeded

      Specifies that an email alert should be sent if the clocks on two different machines in the cluster are more that five seconds apart.

      --alert-communication-issue

      Specifies that an email alert should be sent when nodes are experiencing communication issues.

      --alert-memory-threshold

      Specifies that an email alert should be sent when any node’s system memory usage exceeds a threshold

      HOST FORMATS

      When specifying a host for the couchbase-cli command the following formats are expected:

      • couchbase://<addr>

      • <addr>:<port>

      • http://<addr>:<port>

      It is recommended to use the couchbase://<addr> format for standard installations. The other two formats allow an option to take a port number which is needed for non-default installations where the admin port has been set up on a port other that 8091.

      EXAMPLES

      To enable failover related email alerts for two users without email encryption run the following command below:

      $ couchbase-cli setting-alert -c 192.168.1.5 --username Administrator \
 --password password --enable-email-alert 1 --email-user admin \
 --email-password password --email-host mail.couchbase.com --email-port 25 \
 --email-recipients user1@couchbase.com,user2@couchbase.com \
 --email-sender noreply@couchbase.com --enable-email-encrypt 0 \
 --alert-auto-failover-node --alert-auto-failover-max-reached \
 --alert-auto-failover-node-down --alert-auto-failover-cluster-small \

      To enable all email alerts for a single users with email encryption run the following command below:

      $ couchbase-cli setting-alert -c 192.168.1.5 --username Administrator \
 --password password --enable-email-alert 1 --email-user admin \
 --email-password password --email-host mail.couchbase.com --email-port 25 \
 --email-recipients user@couchbase.com --email-sender noreply@couchbase.com \
 --enable-email-encrypt 1 --alert-auto-failover-node \
 --alert-auto-failover-max-reached --alert-auto-failover-node-down \
 --alert-auto-failover-cluster-small --alert-auto-failover-disable \
 --alert-ip-changed --alert-disk-space --alert-meta-overhead \
 --alert-meta-oom --alert-write-failed --alert-audit-msg-dropped \
 --alert-indexer-max-ram --alert-timestamp-drift-exceeded \

      To disable email alerts run the following command:

      $ couchbase-cli setting-alert -c 192.168.1.5 --username Administrator \
 --password password --enable-email-alert 0

      ENVIRONMENT AND CONFIGURATION VARIABLES
