Given attributes for a node or cluster more information can be found. The following table shows how given one value you can obtain another value.

For example take nodename in the first column then you can use CDBDump to find the clustername or the Operational Procedures to find the sysadmin procedures for a given nodename.

A more complicated example. Suppose you have a clustername and you want to find the remedy category. The table tells you to Get nodenames. To get from clustername to nodenames the table suggests the use of CDBHosts. Now you have the nodenames you can use the table to find the remedy category for each node with CDBDump.

For details on how to use particular tools like CDBHosts or Operational Procedures see below.

Known/Unknown clustername subclustername nodename remedy category lemon alarms sysadmin procedures
clustername = Get nodenames CDBHosts Get nodenames Get nodename Operational Procedures
subclustername Get nodenames = CDBHosts Get nodenames Get nodenames Operational Procedures
nodename CDDump CDBDump = CDBDump lemon-cli Operational Procedures
remedy category ? ? ? = ? ?
lemon alarms ? ? ? ? = Get clustername
sysadmin procedures ? ? Get clustername first ? Get clustername =

Use of CDBDump

On lxplus given a node name you can obtain CDB cluster, subcluster, function, SMS status and contact address for a node. e.g CDBDump fts114 Only nodes in CDB will show anything.

The returned User-contact is the remedy category for the service?

Use of CDBHosts

On lxplus given a cluster name find all the hosts in that cluster. e.g. CDBHosts --cluster gridfts.
Show Example Hide Example 
$ CDBHosts --cluster gridfts
fts006
fts101
fts102
fts103
fts104
fts105
fts106
fts107
fts108
fts109
fts110
fts111
fts112
fts113
fts114
fts115

Again on lxplus given a subcluster you can find all the hosts in a subcluster. I think this assumes that there is a unique namespace for subclusters though which is probably the case? e.g. CDBHosts --cluster=all --subcluster gridwms

Show Example Hide Example 
$ CDBHosts  --cluster=all --subcluster gridwms

wms102

Use of Remedy

To obtain remedy category from a clustername?

Use of lemon-cli

To obtain the list of metrics for a given node use lemon-cli from lxplus. e.g. $ lemon-cli --nodes fts114 --server

> lemon-cli --nodes=fts114 --server
