Re: [1'b68'1 astrad v8] CPU load with notifies to all, every 15 seconds

Done
Yes
Will the program of 3h stop the previous one started at 1h?

01:00 - 03:00
Sending NOTIFY one by one.
03:00 - 05:00
Send 20 notifies in a single command

110619 01:00 - 110619 05:00

110620 01:00 - 110620 05:00

You need to launch the transmission of notifies one by one during 3h then replace it with a transmission 20 by 20. The best is to do this in the middle of the night. You can maybe program this with a cron, such as, until 1:00 nothing, between 1:00 and 3:00 notifies one by one, between 3:00 and 5:00 notifies 20 by 20.

Salut,

Ci-dessous les graphes d’utilisation CPU pour astrad6 et astrad7 avant et après l’activation de Notify (durant la nuit : de 00h à 07h)
L’envoi des Notify est regroupé par 10 depuis hier.
J’ai remarqué que l’utilisation du script optimisé (10 par 10) à une légère amélioration sur l’utilisation CPU mais je n’ai pas suffisamment de donnée pour prouver cette hypothèse.

The second chart shows that notify costs us and is not completely free. You do not indicate the frequency. The chart without frequency is not really informative. The CPU of notify sent one by one must be compared with the CPU of notifies sent in blocks. This will permit to see if we gain anything by sending in blocks.

Did you do this? Try not to invoke the asterisk command for each block of notifies, but rather try to use the same asterisk command and provide to it the input from a file or via a pipe.

Measure the CPU load when sending notifies to 200 clients every 15 seconds. Send 20 notifies in a single command. Do this during 5 minutes and show on the CPU chart, before during, and after.
