Logging is an often frustrating topic when it comes to Dynamics CRM. How do we manage error logging or even debug and verbose/information logging? The answer from Microsoft is simple and standard: use the ITracingService to write logging information. If your requirements are a little more complex, say you need to track your code execution on a very granular level even if no error occurs, then the ITracingService gives you very little options …
- In CRM Online, you cannot activate and review the CRM log files (it’s only available with on premise installations)
- In CRM Online, you can view the details that are related to the job execution (works for Asynchronous plugins and custom WF); For synchronous plugins, you only see the logs if an error is thrown by downloading the log file – there is no permanent record of the log
- If you enable Tracing in CRM (on premise), there is plenty of system written logs in the CRM trace that makes the log file difficult to read and to find your application specific logs, even if you are using the very nice CRM Log Viewer from Stunnware
If you want to have a custom logging module for CRM code, there are a few things to take into consideration:
- What kind of information do you need to log?
- Where do you want/need to write it?
- How and when do you need to access it?
- Do you need to control the logging level at a given time? (write error messages only, verbose, info etc.)
- Who will write the logs? Does that user have permission to write in your chosen location?
Here are a couple of options available to create logs from your CRM code. It is up to the development/architecture team to decide what they want to use that fits their need.
Custom External Logging
You can create logging utilities to write logs in locations other than CRM. For example, you could write logs in the Windows Event Viewer, in a text file or even a custom database. There are also third party tools that help you do that as well (NLog, Log4Net…) if you don’t want to start from scratch. The problem here is that if you are writing logs from plugins or workflow activities that are executed as CRM users, chances are these users won’t have permission to write in your designated location. One option is to simply give access to “Everyone” to these locations but this usually goes against most Enterprises’ IT policies. There are probably ways to set up your log writers to impersonate an admin or user with permissions but I have personally never done it.
- Tailored logging engine built for your needs and in a location of your choice
- Doesn’t work for CRM Online (or not easily)
- Requires system users to have permission to write the logs in the selected location
Custom CRM Entity
Another way to do this is to create one (or many) custom entity to capture your logs. Your CRM custom code can just create new rows in the table(s) to log the required information/error.
- Works for all CRM Installation;
- Security is simple to manage;
- Logging information is available directly in CRM;
- Custom entity can be customized to capture specific logging fields
- Depending on the amount of logging required, your log table(s) may grow really quickly. Think about having a mechanism to clear all unnecessary or outdated logs on a regular basis
- If you are writing logs in a failing transaction, the entire transaction will be rolled back including creation of logging records. Check out a workaround for this issue here.
These are just a few thoughts on logging and as always in technology, there are probably plenty of other things we can do around logging in CRM. Thought this could be helpful. Feel free to reach out if you want more details or guidance on the topic.
As Dynamics CRM consultants, one of the questions that we often get from clients is “how do we archive CRM data when it’s no longer needed”? I’ve seen companies that had to keep all of their data for a certain amount of years for legal reasons. In any case, if you are using Dynamics CRM as a service management tool for a busy call center for example, chances are you are creating a LOT of records at a very fast pace. Imagine having to retain all of the data you created in the past 5 to 10 years on the same system. The size of the database can grow to become extremely large, making every single query a long one and impacting directly the users experience and their trust in the system.
Before I go into details about the available options that I can talk to, here is a quick recap of what Microsoft officially said a while ago about archiving Dynamics CRM data.
- “Archiving implies moving records from one location, storing those records for possible retrieval in another location, and deleting the archived records from the original location.” Given the complexity of the relationships in CRM, archiving as defined in the previous sentence can be very risky and must imply extensive thought, design and knowledge of the CRM application and database.
- An arching solution should not be implemented with the goal of improving system performance.
- Instead of deleting records, it is recommended to deactivate them when they are no longer required.
- The Dynamics CRM application can support very large databases, it is important to make sure that the hardware and database are configured in order to get optimal performance before looking at Archiving.
Here are some possible approaches that can be used to archive your Microsoft Dynamics CRM data. Before going down that path, make sure this is something you really need, don’t just build an archiving solution because you want to improve your system performance. Do your homework first!
||How it work
|1 – Create a copy of the database
||It requires a strong DBA with knowledge of the CRM database to make a copy of the DB, copy all the records that need to be archived to the new DB and finally delete them from their original location. Sounds easy for a DB expert I assume (I’m not!)
- It’s one of the less expensive solution as it only requires a strong DB developer with knowledge of CRM and an available SQL Server database
- Not supported nor recommended by Microsoft
- A DBA with knowledge of the Dynamics CRM database is always required to retrieve data from the archive database
|2 – Create a new instance of Dynamics CRM
- The archived records are easy to retrieve (same UI as prod)
- Access to these records can be controlled by the Dynamics CRM security model
- Can be done in a supported way
- Expensive solution that may requires additional hardware, server and/or user licenses for CRM or SQL Server
- Company ends up maintaining more than one CRM organizations in the long run
|3 – Deactivated unwanted records and tweak database Indexes
|This is easily the number 1 choice from Microsoft’s perspective. To me, this should be one of the drivers in the CRM application design. The lifecycle of all records that are created (except for master data) should always be to:
- create record (with active state obviously)
- do work
- deactivate record after the job is complete (set state to inactive)
In many systems that I have seen, some records just remain active forever, even though they are old and on longer required in the active records view.
Also, it is important to create SQL indexes to enable a faster retrieval of active records.
- This method does not involve the deleting on any record from the CRM database which is what MS recommends
- It forces the application to be designed with best practice for records lifecycle management
|I could write down that the down side is that records remain in the CRM database but again, you are not archiving simply because you want to reduce the size of your database…
|4 – Create and store custom archive reports
||This is an interesting one. I’ve personally recommended using this solution to capture the history of successful workflows execution prior to deleting them from the system.
The idea is to create custom reports containing information from the records that are no longer needed in the system. Once the reports have been created, they can be stored in a document management system or sent by email. After that, then the records can be deleted from the CRM database.
There are many ways to create reports in CRM so I won’t spend time discussion that topic here. A simple Google (or should I say Bing searchJ) will give you plenty of starting points.
- Lots of options for reports creation and execution (3rd party software, SSRS, scheduling jobs, custom workflow activities etc.)
- Can be done in a supported way
|5 – Create a custom Archive Database
|This is very similar to option 2. The difference would be instead of creating a new instance of CRM, you can create a custom database where you would only keep the information that you need. This database would be populated by a custom .NET app, third party data migration tool routine or database scripting.
Optionally, a custom UI can be developed to enable administrators to search through the custom database.
- Tailored archiving solution, enables for more granularity and focus on retaining only the information that is required
- If done well and if CRM solution(s) doesn’t evolve too much over time, it’s a one effort and maintenance should be easier than maintaining 2 CRM instances
- Can be done in a supported way
- Expensive to build (requires deep analysis and development time)
- Custom database must be maintained
- Security is no longer controlled by the Dynamics CRM application
I personally like solution 5 better but it’s only because I’m a developer and I’d enjoy having to design the new database and the archiving tool. Of course, every company has its own preferences and resources with different set of skills. This should all be taken into consideration prior to deciding what solution to use. These are only the ones that I came up with, there are certainly other options out there.
Hope this helps!
