L'exemple suivant illustre un workflow créant une feuille de travail à partir d'un type de lecteur donné :
Exemple 4-13 Sélection du type de périphérique de workflowvar 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 = 'Drilling down on ' + params.type + ' disks'; 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: 'Finding disks of specified type', execute: function (params) { /* * In this step, we will iterate over all chassis, and for * each chassis iterates over all disks in the chassis, * looking for disks that match the specified type. */ var chassis, name, disks; var i, j; run('cd /'); run('maintenance hardware'); chassis = list(); params.disks = []; for (i = 0; i < chassis.length; i++) { run('select ' + chassis[i]); name = get('name'); run('select disk'); disks = list(); for (j = 0; j < disks.length; j++) { run('select ' + disks[j]); if (get('use') == params.type) { params.disks.push(name + '/' + get('label')); } run('cd ..'); } run('cd ../..'); } if (params.disks.length === 0) throw ('No ' + params.type + ' disks found'); run('cd /'); } }, { step: 'Creating worksheet', execute: function (params) { /* * In this step, we're ready to actually create the worksheet * itself: we have the disks of the specified type and * we know that we can create the worksheet. Note that we * create several datasets: first, I/O bytes broken down * by disk, with each disk of the specified type highlighted * as a drilldown. Then, we create a separate dataset for * each disk of the specified type. Finally, note that we * aren't saving the datasets -- we'll let the user do that * from the created worksheet if they so desire. (It would * be straightforward to add a boolean parameter to this * workflow that allows that last behavior to be optionally * changed.) */ var disks = [], i; run('analytics worksheets'); run('create "' + params.worksheet + '"'); run('select name="' + params.worksheet + '"'); run('dataset'); run('set name=io.bytes[disk]'); for (i = 0; i < params.disks.length; i++) disks.push('"' + params.disks[i] + '"'); run('set drilldowns=' + disks.join(',')); run('commit'); for (i = 0; i < params.disks.length; i++) { run('dataset'); run('set name="io.bytes[disk=' + params.disks[i] + ']"'); run('commit'); } } } ]; var workflow = { name: 'Disk drilldown', description: 'Creates a worksheet that drills down on system, ' + 'cache, or log devices', parameters: { type: { label: 'Create a new worksheet drilling down on', type: 'ChooseOne', options: [ 'cache', 'log', 'system' ], optionlabels: [ 'Cache', 'Log', 'System' ] }, overwrite: { label: 'Overwrite the worksheet if it exists', type: 'Boolean' } }, execute: function (params) { return (steps); } };
