• 5 questions you should ask yourself before defining a custom alert in Matomo

  24 janvier 2018, par InnoCraft

  In Matomo, you can create Custom Alerts to automatically be notified of important changes on your website or app. They are a great way to save time, but they also spam your mailbox quickly. Defining good custom alerts takes therefore time and requires some preparations. Here are recommendations on what you should focus on to only get the right alerts at the right time.

  There are several questions you should ask yourself before you define a custom alert :

  1. Do you really want to be alerted ? If the answer is no, then do not use this feature.
  2. What is the level of this alert ? Not important, interesting, highly critical… if it is not highly critical, do not define an alert for this. Probably the emailing report or custom reports feature will be a better fit.
  3. How would you like to be alerted ? SMS, email, sound, homing pigeon (unfortunately we do not support this feature at that time). If you are looking at your emails once a week, then defining a daily email alert won’t make sense.
  4. How would you like the alert to be named ? Give your alert the most explicit name, that’s the first information you will see when you get alerted.
  5. What will be the next step once the alert is triggered ? If you cannot find any action once the alert is triggered, then probably an alert doesn’t make sense.

  Once those questions are answered, you can start configuring custom alerts. There are many alerts you can define but as just mentioned, which alerts you should create always depends on your goals and what is critical to you, or your business. Let’s look at some custom alerts that we see quite often.

  No visit

  One of the easiest custom alert to define. You probably want to be alerted if your website did not receive any visit. As this alert is highly critical, you will want to receive an e-mail, even an SMS. This alert will trigger only if the number of visits is below 1 on a daily basis :

  

  Here the action we will take is to have a look at the website in order to see if it is still live. If the site still works, we will look at the tracking code in order to see if the website is still correctly tracked or not.

  Convinced of this custom alert ? Let’s look at another example.

  Target achieved

  Let’s say you gave a goal to one of your employee to reach a specific threshold in terms of conversions. You can then define a custom alert in order to inform you when the threshold has been reached.

  You can simply do this with an alert saying “Target achieved by Franck” where number of conversions equals the number of actions you defined with him. It takes you only a minute to define something you would have missed otherwise.

  

  Here the actions we can think of are either to congratulate Franck or to ask him what is going wrong if the target is not achieved.

  Did you know that you can also take advantage of Matomo premium features to define custom alerts ? Let’s see one of them.

  Lost SEO ranking

  If you are using the Search Engine Keyword Performance premium feature, there are really interesting combinations you can use to create custom alerts.
  For example, you can be notified when a specific keyword lost or reached a position :

  

  You will be alerted when your website is losing some positions within the search engine results for specific keywords. Here the action we could take is to investigate why we lost a position on Google for this keyword.

  There are many custom alert combinations waiting for you out there. Why not giving them a try ? If you have any questions, feel free to ask them on the Matomo forums.

• Official RealVideo Specifications

  29 juillet 2010, par Multimedia Mike — General

  A little birdie tipped me off to a publicly-accessible URL on the Helix community site (does anyone actually use Helix ?) that contains a bunch of specifications for RealVideo 8 and 9. I have been sifting through the documents to see exactly what they contain as the different files seem to be higher revisions of the same documents. Here is the title, date, and version of each PDF document :

  • RNDecoderPerformanceARM.pdf : Decoder Performance on StrongARM and XScale ; May 12, 2003 ; Version 1.1
  • rv89_decoder_summary.pdf : RealVideo 8/9 Combo Decoder Summary ; October 23, 2002 ; Version 1.0
  • rv9_dec_external_spec_v14.pdf : RealVideo 9 External Specification ; November 7, 2003 ; Version 1.4
  • rv8_dec_external_spec_v20.pdf : RealVideo 8 External Specification ; September 19, 2002 ; Version 2.0
  • RV8DecoderExternalSpecificationv201.pdf : RealVideo 8 External Specification ; October 20, 2006 ; Version 2.01
  • RV8DecoderExternalSpecificationv202.pdf : RealVideo 8 External Specification ; April 23, 2007 ; Version 2.02
  • RV8DecoderExternalSpecificationv203.pdf : RealVideo 8 External Specification ; July 20, 2007 ; Version 2.03
  • RV8DecoderExternalSpecificationv21.pdf : RealVideo 8 External Specification ; September 11, 2007 ; Version 2.1
  • RV9DecoderExternalSpecificationv15.pdf ; RealVideo 9 External Specification ; January 26, 2002 ; Version 1.5
  • RV9DecoderExternalSpecificationv16.pdf ; RealVideo 9 External Specification ; August 17, 2005 ; Version 1.6
  • RV9DecoderExternalSpecificationv18.pdf ; RealVideo 9 External Specification ; September 11, 2007 ; Version 1.8

  Additionally, there is an Excel spreadsheet entitled realvideo-faq.xls that appears to contain some general tech support advice for using Real’s official code. There are also 3 ZIP archives which contain profiling information about the official source code (post processing and entropy decoding top the charts which is no big surprise).

  I guess the latest version of each document (the ones dated September 11, 2007) are worth mirroring. Unfortunately, those latest document versions use a terrible font.

• how to ignore or fix false 'unmet dependencies' error ?

  31 août 2014, par yy502

  OS: LMDE 201403

  I previously installed OpenShot (a video editing software), which depends on libmlt6, and libmlt6 depends on ffmpeg. The chain of dependencies auto-installed just fine.

  Today I compiled and installed the latest ffmpeg v2.3.3 and apt-get starts to complain :

  You might want to run 'apt-get -f install' to correct these:
  
  The following packages have unmet dependencies:
  
   libmlt6 : Depends: ffmpeg (>= 5:0.6.2~) but 2.3.3-1 is to be installed
  
  E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).

  Well, I’m sure my compiled version of ffmpeg is newer than whatever version libmlt6 requires, but the package manager does not seem to understand the new version number. How can I ignore or fix false ’unmet dependencies’ error, please ?

  Thanks for your time !

  Edit :

  Executing apt-get -f install would install the ffmpeg from repository to /usr/bin/ and uninstall/overwrite my compiled version of ffmpeg in /usr/local/bin/... not really the solution I’m after...

  Edit2 :

  the auto fix of apt-get will remove my compiled version of ffmpeg as prompted below :

  sudo apt-get install -f
