Schedule a report using cron

Hi all,

I am trying to schedule a report to run every 4 hours (every day) and spit out VMs with active snapshots. I have got the this same report using powershell, but as we have VMAN, I want to make the most of it.

To achieve this I am using the out of box report: VMs With Snapshots, then schedule a cron as follows:

I have tried to use the conventional cron syntax: 01 */4 * * *

but might need to add Seconds http://knowledgebase.solarwinds.com/kb/questions/4058/Cannot+create+a+new+scheduled+report+with+the+Cron+option

therefore my final syntax reads as follows:

seconds minutes hours dayofmonth month dayofweek

however I get the following error:I have checked time, etc and it is all okay

Could someone assist me please??

thanks in advance, rb51
