..at the risk of actually getting feedback, I'm asking for feedback !
Using the perl interfaces to NetApp's Ontap and DFM SDK, I've written a script that
can display certain protection manager events. It can display individual schedules or schedules attached
to a policy. I have a prototype working and I looking for feedback on what else might go
into the tool or how to better present the output.
Where' the way it works.
> /usr/software/bin/perl sched.pm -h
SYNTAX:
[-b <date>] -d <duration> (-s <schedule> | -p <policy>)
-l (pols | scheds)
-h | --help
Arguments definitions are
-b <date> : specify the start date
: this argument pair is optional and if not specified then today's date is used
: <date> format can be any of
: DD -means a day in current month and year
: Mon-DD -means a month and a day of month in the current year
: Mon-DD-YYYY -means a month, day, and year in this existance
: DD does not have to be two digits, Mon should be first 3 letters of month
-d <duration> : specify the length of time
: <duration> must be a number between 1 and 100, followed by
: d for days
: w for weeks
: m for months
-s <schedule> : specify the schedule
: <schedule> can be either the sched's name or the sched's DFM ID
-p <policy> : specify the policy
: <policy> can be either the policy's name or the policy's DFM ID
-l (pols | scheds) : list policies or list schedules
Be sure to use quotes around policy or schedule names that have spaces (eg. 'Back up')
OUTPUT format is: <TIME> <EVENTS>
Where <TIME> is expressed as MM-DD HH:MM
and <EVENTS> represents one or more scheduled snapshots for that <TIME>.
Hourly means an hourly snapshot is schedule. Daily, Wkly, Monthly are the
other possibilities.
EXAMPLE:
> sched.pm -b Oct-20 -d 5d -s 'Daily at 8:00 PM'
Here's a couple actual runs of the prototype
### Show 5 days of the 'Daily at 8:00PM' schedule
#
> /usr/software/bin/perl sched.pm -b Oct-20 -d 5d -s 'Daily at 8:00 PM'
| Daily at 8:00 PM |
===========================
Oct-20 20:00 | daily, |
Oct-21 20:00 | daily, |
Oct-22 20:00 | daily, |
Oct-23 20:00 | daily, |
Oct-24 20:00 | daily, |
#### Show 2 weeks of a three node policy. I created the policy and used two
#### schedules I created, SimpleDaily and SimpleWeekly
#
> /usr/software/bin/perl sched.pm -d 2w -p 'Backup, then mirror'
Primary Node Connection 1 Connection 2
(SimpleDaily) (SimpleDaily) (SimpleWeekly)
===========================================================
Oct-15 09:04 | hourly, | hourly, | |
Oct-15 14:54 | hourly, | hourly, | |
Oct-15 20:44 | hourly, | hourly, | |
Oct-15 22:05 | daily, | daily, | |
Oct-16 09:04 | hourly, | hourly, | |
Oct-16 14:54 | hourly, | hourly, | |
Oct-16 20:44 | hourly, | hourly, | |
Oct-16 22:00 | | | weekly, |
Oct-16 22:05 | daily, | daily, | |
Oct-17 09:04 | hourly, | hourly, | |
Oct-17 14:54 | hourly, | hourly, | |
Oct-17 20:44 | hourly, | hourly, | |
Oct-17 22:05 | daily, | daily, | |
Oct-18 09:04 | hourly, | hourly, | |
Oct-18 14:54 | hourly, | hourly, | |
Oct-18 20:44 | hourly, | hourly, | |

The script is currently hardcoded to talk to a specific dfm server with a specific user and password.
Obviously I'll add those as arguments when I publish the script.
Feedback ...
