I wrote this script a little while ago, but I wanted to re-write it so I could share it. Originally, I had our API key, email addresses, and smtp server address hard coded into the script. I obviously didn’t want to share that, and I didn’t want anyone to have to open the script and find and edit text. This led me to figure out how to save to XML, something I haven’t done yet as a beginner.

To give a little background of why I wrote this script, let me start by saying how lazy and forgetful I can be. We are a partner of Datto who we use for our backup solutions. Without getting into too much detail of the backups, it is a managed service we provide, which means we have to monitor the backups for our clients and resolve any backup issues. To check the backups of all our clients, we simply login to Datto’s partner portal and drill down into each appliance to check the statuses. There are two problems that I already highlighted. One, I can be pretty lazy, so logging in and drilling down into each appliance is a pain in the butt for me. Two, I can be forgetful, so depending on myself to remember to login and check all these servers when I happen to walk into fire fighting first thing in the morning is not the most reliable way to make sure backups get checked. This is where the script comes in thanks to Datto’s XML API.

Using this script, I can pull the backup statuses for all the servers and have them formatted in a nice email that I know I will read. I have this script running first thing in the morning and at lunch time, as our backups are hourly and I want to make sure there haven’t been any servers without backups for more than a few hours.

The way the script works is you run the script with a -config option to generate the XML file it will use to store is configuration. It will ask you for your API key, email subject, from address, to address, and SMTP server address. After the file is generated, you simply run the script itself without any options. It will grab the info from that file, grab the info from Datto, generate the email, and send it to you in a tabular format similar to the following:

CLIENTA:
Server Name Status Last Snapshot
CLIENTA-SRV1 Success 2013-05-28 11:03:19
CLIENTB:
Server Name Status Last Snapshot
CLIENTB-SRV1 Success 2013-05-28 11:10:05
CLIENTB-SRV2 Success 2013-05-28 11:08:37
CLIENTB-SRV3 Success 2013-05-28 11:08:39

Schedule this with cron on Linux or Task Scheduler on Windows, and you can save yourself the time of logging into Datto’s website and drilling down into each appliance.

Eventually, I plan on adding to this script to update a custom field in our RMM platform. The field will be something like last backup or maybe two fields, last successful backup and last backup status. Then if the time since the last successful backup gets too far out, I can have our RMM generate a support ticket. Then I won’t even have to look at the email. Lazy or efficient?

There are a couple other things I may change or just try with future scripts. After writing this, I read about the python module OptParser, which seems like a much better way to handle command line options for your script than the way I’ve been doing them. Also, I’m thinking about changing the configuration settings from XLM to using the Pickle module. It seems much simpler. I would have played with those changes before posting this, but I’m getting ready to head off to training on Business Continuity in Philadelphia and won’t have time.

Oh yeah, I wasted a lot of time trying to figure out how to make this script run no matter if you are on Python 2.7 or Python 3. After putzing around, I found the only thing I needed to do was add the following lines. It worked like a champ.

As always, if you have any recommendations, let me know. Here’s the code.

Below is a script that I wrote to address a problem we were having at our clients. Most of our clients have their email hosted on Appriver. They are hosted with Exchange 2010. All the sudden out of the blue, users start reporting that Outlook is not connecting to the servers or if it does connect, it’s not very long before it disconnects. We contacted Appriver to see if they were having issues. It turns our Microsoft put a patch out that was causing XP machines to have issues connecting to the Exchange 2010 farm. The workaround was to put an entry into the host file for the front end server.

So now that I had the fix, did I want to connect to every XP machine and edit the host file. Hell no. To quickly fix this, I wrote a down and dirty version of this script with the host entry statically in the script. It was 4 lines, simply opening the host file, writing the line and closing the file. I then used our RMM, Labtech, to create a script that would run this on XP machines. We ran it and within seconds of it running on the computers, email was working again.

Obviously, it would be bad if this script ran repeatedly on the same computer as it would put duplicate host entries. Now that the fire was out, I wanted to write a version that I could use repeatedly in the future if needed by just passing an IP address and hostname to the script. Unlike my quick fix, the reusable script would have to have some checks built in. It would have to check to make sure the host wasn’t already in the host file, and it would have to make sure the IP address and the hostname is valid.

Here’s what I have so far. I’d like to add the ability to delete an entry and to update an entry as well. In order to run this on Linux, you must run sudo, su, etc. On Windows, you’ll want to run as administrator. Luckily, we’re able to do that via our RMM platform.

Let me know your thoughts. I’m sure there are many ways to improve this, and I’m sure there are other ways to do it.

 

For those of you not following this mess of me learning to program in Python, this is the third option so far for getting Dell warranty expirations via web scraping. The first option I posted was the one I did without any direction from anyone who knows what they are doing. I used a string function. You can read that post here. After I posted that version on Google+ and Reddit, I got recommendations to do this with regex, Scrapy and BeautifulSoup. My last post was getting the expiration date via regex. This post is getting it with BeautifulSoup, which I must say once I figured out how to do what I wanted was much better.

Here’s a quick run down of how I’m doing this. Again, I’m sure some of this could be done much better.

The modules I use are sys for getting the command line arguments, requests to pull the data from Dell.com, and lastly BeautifulSoup to parse the html. The function is only a few lines. First, I pull the html from Dell followed by parsing it with BeautifulSoup. Next, I find all the TopTwoWarrantyListItems and assign to the variable lis. Lastly, I compare those list items to pull out the max value which is assigned and returned as the warranty expiration date.

Let me know what you think, good and bad. Every time I post one of these, I get some new advice that helps me learn.
