Sun Microsystems 7000 manual Appendix, Select Maintenance -Workflows Click + to Add a Workflow

5.0 Appendix

This appendix contains a sample workflow script to build an Analytics worksheet for monitoring NFSv3 and iSCSI operations. This workflow should be copied to a text file and then uploaded to the Sun Storage 7000 Unified Storage System by taking the following steps:

1.Select Maintenance ->Workflows.

2.Click (+) to Add a Workflow.

3.Browse to the text file location.

4.Activate Workflow by double-clicking on the name of the workflow.

5.The resulting worksheet can be accessed by selecting Analytics -> Saved Worksheets. Below is a workflow example:

/*

*This is an example workflow for building a Analytics worksheet

*The worksheet is intended to monitor key metrics for NFSv3 and

*iSCSI operations in a VMware ESX environment

*

*/

var steps = [ {

step: 'Checking for existing worksheet',

execute: function (params) { /*

*In this step, we're going to see if the worksheet that

*we're going to create already exists. If the worksheet

*already exists, we blow it away if the user has indicated

*that they desire this behavior. Note that we store our

*derived worksheet name with the parameters, even though

*it is not a parameter per se; this is explicitly allowed,

*and it allows us to build state in one step that is

*processed in another without requiring additional global

*variables.

*/

params.worksheet = 'VMware ESX Worksheet';

try {

run('analytics worksheets select name="' + params.worksheet + '"');

if (params.overwrite) { run('confirm destroy'); return;

}

throw('Worksheet called "' + params.worksheet + '" already exists!');

} catch (err) {

if (err.code != EAKSH_ENTITY_BADSELECT) throw (err);

}

}

}, {

step: 'Creating worksheet',

execute: function (params) { /*

*In this step, we're ready to actually create the worksheet

*itself. Finally, note that we

*aren't saving the datasets -- we'll let the user do that
