OCF_HEARTBEAT_OVSMON(7) OCF resource agents OCF_HEARTBEAT_OVSMON(7) NAME ocf_heartbeat_ovsmonitor - Monitors ovs bonding bonds SYNOPSIS ovsmonitor [start | stop | status | monitor | meta-data | validate-all] DESCRIPTION Monitor the vitality of a local ovs bond. You may set up this RA as a clone resource to monitor the network bonds on different nodes, with the same bond name. This is not related to the IP ad- dress or the network on which a bond is configured. You may use this RA to move resources away from a node, which has a faulty bond or prevent moving resources to such a node. This gives you independent control of the re- sources, without involving cluster intercommunication. But it requires your nodes to have more than one network bond. The resource configuration requires a monitor operation, because the moni- tor does the main part of the work. In addition to the resource configura- tion, you need to configure some location constraints, based on a CIB at- tribute value. The name of the attribute value is configured in the 'name' option of this RA. Example constraint configuration using crmsh location loc_connected_node my_resource_grp rule ="rule_loc_connected_node" -INF: ovsmonitor-bond-pub- lic eq 0 Example constraint configuration using pcs. Only allow 'my_resource' to run on nodes where eth0 ethernet device is available. pcs constraint location my_resource rule score=-INFINITY ovsmonitor-bond-public ne 1 The ethmonitor works in 3 different modes to test the bond vitality. 1. call ovs-appctl to see if at least one of the bonding's link status is up (if link is down -> error) 2. call ovs-ofctl and watch the RX counter (if packages come around in a certain time -> success) 3. return error SUPPORTED PARAMETERS bond The name of the network bond which should be monitored (e.g. bond-pub- lic). (unique, required, string, no default) bridge The name of the ovs bridge that contains the bridge. (unique, required, string, no default) name The name of the CIB attribute to set. This is the name to be used in the constraints. Defaults to "ovsmonitor-'bond_name'". (unique, optional, string, no default) multiplier Multiplier for the value of the CIB attriobute specified in parameter name. (optional, integer, default 1) repeat_count Specify how often the bond will be monitored, before the status is set to failed. You need to set the timeout of the monitoring operation to at least repeat_count * repeat_interval (optional, integer, default 5) repeat_interval Specify how long to wait in seconds between the repeat_counts. (optional, integer, default 10) pktcnt_timeout Timeout for the RX packet counter. Stop listening for packet counter changes after the given number of seconds. (optional, integer, default 5) link_status_only Only report success based on link status. Do not perform RX counter re- lated connectivity tests. (optional, boolean, default false) SUPPORTED ACTIONS This resource agent supports the following actions (operations): start Starts the resource. Suggested minimum timeout: 60s. stop Stops the resource. Suggested minimum timeout: 20s. status Performs a status check. Suggested minimum timeout: 60s. Suggested in- terval: 10s. monitor Performs a detailed status check. Suggested minimum timeout: 60s. Sug- gested interval: 10s. meta-data Retrieves resource agent metadata (internal use only). Suggested mini- mum timeout: 5s. validate-all Performs a validation of the resource configuration. Suggested minimum timeout: 20s.
