SnapMirror log parser

Hello,

While looking at a way to automate SnapMirror logs extraction and consolidation, I've found Get-NaSystemLog -SnapMirror in the toolkit.

I've written a script close to the parser available in Tool Chest on support website, feel free to send me your comments.

Script requires PS toolkit, so if not loaded, change path to it accordingly in the script.

NEW VERSION 0.2 with following changes:

- Added "Last" parameter to process only <X> last lines from SnapMirror log

- Fixed transfer hash valid key detection

Enjoy!

Michel,

Nice work!  Definitely helpful.  I'm wondering if some code could be added to have an option of opening a copy of the snapmirror log from a local drive (well, I'm sure it could be, I'm still cutting my teeth on PS still so I'm challenging myself to figure it out too!).

Re: SnapMirror log parser

Thanks!

I had a quick look and there's -Path parameter:

Get-NaSystemLog -SnapMirror [-EventType <String[]>] [-StartTime <DateTime>] [-EndTime <DateTime>] [[-Path] <String>] [-Follow] [-Controller <NaController>] [<CommonParameters>]

Unfortunately -Controller parameter is mandatory, meaning it can't parse a local file, but you could possibly copy the file you got to a local Filer, then parse that specific file:

PS C:\temp> Get-NaSystemLog -SnapMirror -Path /vol/vol0/etc/log/snapmirror.mg
