Re: [SR-Users] Keep Number of Messages per Source

Look at the definition of htable parameter, there you have various ways to set expires for each item in hash table.

Thanks Alex,

This is exactly the module I needed. Now just another small usage question. How can I reset the value of all entries in my hash table to 0 every, say "10" seconds?

---

Here is what I tried, but the values seem to persist:

Option 1) in the parameter definition set "initval" to 0 (to have all items 0 initially), "autoexpire" to "10" seconds and "updateexpire" to 0 (to force expiration upon the end of 10 seconds)

Option 2) Create a fake route block executed every 10 seconds (using "rtimer" module), and call "sht_rm_value_re("ha=>.*")" inside it.

None of these seem to be resetting "all" of my entries in the hash table to 0, in fact, I can see that the values persist and continue increment (as I increment them upon receipt of messages). Am I missing sth here?

Thanks Alireza

    Hi List,

    I am trying to keep a counter for number of messages received
    per source
    ip in my kamailio script.

    The basic challenge is to keep this data in a neat structure.
    Ideally, I want some array with keys named after source IP
    addresses,

    sth like number_of_messages["10.10.10.10"] = 23

    Of course, this data structure shall be script-persistent (as
    opposed to
    transaction persistent)

    Is there any suggestion to do this? (keep a record of # of
    messages
    received from each source IP address and log them)?


It sounds to me like you're looking for:

http://kamailio.org/docs/modules/4.1.x/modules/htable.html

The hash tables reside in shared memory, so the data is of global
scope and script-persistent.
