OCF_HEARTBEAT_GCP-I(7) OCF resource agents OCF_HEARTBEAT_GCP-I(7)

NAME

ocf_heartbeat_gcp-ilb - Replies to health checks from Google Cloud

SYNOPSIS

gcp-ilb [start | stop | monitor | meta-data | validate-all]

DESCRIPTION

Resource Agent that wraps /usr/bin/nc or /usr/bin/socat to reply to health checks in Google Cloud. See https://cloud.google.com/load-balancing/docs/health-checks for more information.

SUPPORTED PARAMETERS

port

Listening port for health-check probes. Default: 60000

(optional, string, default "60000")

cat

Location of netcat (default: /usr/bin/nc ) or socat (default: /usr/bin/socat ). If present, is used /usr/bin/socat. The recommended binary is socat, present in the following minimum versions if the package resource-agents: - SLES 12 SP4/SP5: resource-agents-4.3.018.a7fb5035-3.30.1. - SLES 15/15 SP1: resource-agents-4.3.0184.6ee15eb2-4.13.1.

(optional, string, default "nc")

log_enable

Logging with an external application is enabled (accepts "true" or "false"). The defaults are configured to call "gcloud logging" (see: https://cloud.google.com/sdk/gcloud/reference/logging).

(optional, string, default "false")

log_cmd

External logging command. The defaults are configured to call "gcloud logging" (see: https://cloud.google.com/sdk/gcloud/reference/logging). This parameter should only have the binary that can be validated (e.g., gcloud). The rest of the command is formed with the additional parameters and the message being logged as follows: - log_cmd + log_params + "The message being logged" + log_end_params Using the gcloud command for Stackdriver logging, the parameters would be: - log_cmd = gcloud - log_params = logging write GCPILB - "This is a message being sent by the app" - log_end_params = (nothing in this case, this is reserved for use with other tools) Which would result in this valid command (where GCPILB is the name of the log): gcloud logging write GCPILB "This is a message being sent by the app"

NOTE: Only the binary is validated for existence and no further checks are performed. The assumption is that only administrators with root access can configure this tool.

(optional, string, default "gcloud")

log_params

Additional input for the logging application. See explanation for log_cmd

(optional, string, default "logging write GCPILB")

log_end_params

Additional input for the logging application. Placed after the message being logged.

(optional, string, no default)
