  • ffmpeg azure function consumption plan low CPU availability for high volume requests

    27 novembre 2017, par The Lemon

    I am running an azure queue function on a consumption plan ; my function starts an FFMpeg process and accordingly is very CPU intensive. When I run the function with less than 100 items in the queue at once it works perfectly, azure scales up and gives me plenty of servers and all of the tasks complete very quickly. My problem is once I start doing more than 300 or 400 items at once, it starts fine but after a while the CPU slowly goes from 80% utilisation to only around 10% utilisation - my functions cant finish in time with only 10% CPU. This can be seen in the image shown below.
    Does anyone know why the CPU useage is going lower the more instances my function creates ? Thanks in advance Cuan

    edit : the function is set to only run one at a time per instance, but the problem exists when set to 2 or 3 concurrent processes per instance in the host.json

    edit : the CPU drops get noticeable at 15-20 servers, and start causing failures at around 60. After that the CPU bottoms out at an average of 8-10% with individuals reaching 0-3%, and the server count seems to increase without limit (which would be more helpful if I got some CPU with the servers)

    Thanks again, Cuan.

    I’ve also added the function code to the bottom of this post in case it helps.

  • Evolution #4462 (Nouveau) : Rendu du plan

    20 mars 2020, par jluc -

    Sur la page ?exec=plan on peut déployer l’arborescence des rubriques. Il y a toutefois un déficit d’indications visuelles sur cette possibilité car
    - lorsqu’on hover le nom d’une rubrique, le style change et on sait qu’on peut cliquer, mais lorsqu’on clique sur le nom d’une rubriques on est projeté vers la page de cette rubrique, dans le même onglet
    - il y a bien un minitruc pâlot triangulaire à gauche, mais il ne change pas de style au survol (à part le pointeur de la souris) et sa minitaille et son faible contraste n’invitent pas au survol, et le simple changement de curseur invite mal au clic. C’est pourtant lui qu’il faut cliquer pour déployer la rubrique.

    Il serait utile de bénéficier d’indications plus claires facilitant l’usage de l’arbre du plan.
    - peut être un ’+’ plus gros et plus contrasté que ce triangle
    - et en tout cas, un changement d’apparence au survol (+ un title ?)
    - une indication textuelle sur ce que permet cette page (le compagnon le fait il déjà peut être ?). Par exemple "Vous pouvez déployer les rubriques en cliquant le + ou le triangle à gauche, et vous pouvez déplacer les rubriques et leur contenu dans l’arborescence par glisser-déposer"
