Hi!

I’m having some issues with dispatcher and cannot get why it’s not working

Idea is to use ds_next_dst right after ds_select_dst

I’m having it like this

modparam("dispatcher", "list_file", "/tmp/dispatcher.list") modparam("dispatcher", "flags", 2) # Enable dispather failover modparam("dispatcher", "xavp_dst", "_dispacher_dst_list_") …

ds_select_dst(«1», «0»);

Maybe a problem with the style of quotation marks you used there?

...

... # Some extra check on $du here … ds_next_dst();

But get in logs WARNING: dispatcher [dispatch.c:2285]: ds_update_dst(): no xavp uri field in next destination record

But contents of /tmp/dispatcher.list is 1 sip:172.28.0.12:5060 1 sip:172.28.0.19:5060

Can I somehow dump xavp_dst var to check if ds_select_dst is correct?

Made a pv_xavp_print() afrer ds_select_dst

You could use pv_xavp_print(): https://www.kamailio.org/docs/modules/5.1.x/modules/pv.html# pv.f.pv_xavp_print

If there is a better way I'd like to know myself.

Try with ds_select_next() in failure_route[]

On Fri, Aug 31, 2018 at 06:17 Igor Olhovskiy igorolhovskiy@gmail.com wrote:

Tried other way round All of this is happening in FAILURE ROUTE.

ds_mark_dst("d"); ds_select_dst("1", "0")

But ds_select_dst still selecting for me gateway already marked with "d" on previous step. Seems, it applying states after packet sent. And any other way I can select new dst from set?

Idea why I'm using ds_select_dst in FAILURE_ROUTE and not ds_next_dst() that during failover timer dispatcher list could change (yes, it could be extensive process) and I want to use most fresh version.

Can I somehow dump xavp_dst var to check if ds_select_dst is correct?

You could use pv_xavp_print():

If there is a better way I'd like to know myself.

Is there any way to select not first destination from ds_select_dst()? Could not find any way to do this...

Sorry, hit sent too soon.

I meant ds_next_dst() or ds_next_domain():

Try with ds_select_next() in failure_route[]

Tried other way round All of this is happening in FAILURE ROUTE.

ds_mark_dst("d"); ds_select_dst("1", "0")

But ds_select_dst still selecting for me gateway already marked with "d" on previous step. Seems, it applying states after packet sent. And any other way I can select new dst from set?

Idea why I'm using ds_select_dst in FAILURE_ROUTE and not ds_next_dst() that during failover timer dispatcher list could change (yes, it could be extensive process) and I want to use most fresh version.

Hi! I’ve used ds_select_dst() and ds_next_dst() one after another in failure route. If use in request/failure it’s working ok.

But again, during the failover in my environment dispatcher list can change. And I don’t want to rely on ds_next_dst() cause it can bring me absent node. So, I’ve been thinking of use xavp variable to get data from it, but still can’t get it to work.

I think you are confused between:

ds_select_dst() = get a node from the dispatcher group based on weight and priority. Use in request_route.

ds_next_dst() = get the next node from the list previously created with ds_select_dst(). Use this in failure_route.

Give it a try and let us know.

Is there any way to select not first destination from ds_select_dst()? Could not find any way to do this...

Sorry, hit sent too soon.

I meant ds_next_dst() or ds_next_domain():

Try with ds_select_next() in failure_route[]

An example could be like this

3 nodes (A, B, C)

INVITE 1 -> ds_select_dst() -> Node A INVITE 2 -> ds_select_dst() -> Node A A dies B replaced C replaced  - external calls dispatcher.reload with new node list A (yes, died state), E, F INVITE 1 -> failure_route, ds_mark_dst() as Disabled  but with ds_next_dst() does not know anything about E or F, and B and C already out of order. So, my solution is again call ds_select_dst() in failure_route, but it can return Node A (which is dead and I know it already). So, I’m trying to select next node, with ds_next_dst() to select Node E, but calling this command gives me WARNING: dispatcher [dispatch.c:2285]: ds_update_dst(): no xavp uri field

If it brings the failed it’s because when it was marked as disabled that node was already in the list, so it will fail and hit the failure route again and move to next node.

The next call of ds_select_dst (in request route) will populate a list without disabled nodes, etc.

To summarize:

• In request route call ds_select_dst()
• if it fails, in failed_route call ds_mark_dst() and then ds_next_dst()

Example:

...to keep it easy to understand, let's pretend that dispatcher doesn't load balance and just failsover, let's say you have a ds group of nodes A, B and C...

• INVITE 1 received. ds_select_dst() (the list contains A, B, C). $du=A
• INVITE 2 received. ds_select_dst() (the list contains A, B, C). $du=A
• A dies.
• INVITE 1 in failure route, A is maked as disabled, ds_next_dst() (updated list contains B and C). $du=B
• INVITE 3 received, ds_select_dst() (the list contains B, C). $du=B
• INVITE 2 in failure route, A is already marked as disabled, ds_next_dst() (updated list contains B and C). $du=B
• ...people talk via server B because A failed...

So really you would only send calls that populated the dispather list before dying, after that the next calls wouldn't even try to hit that server.

Can you give some more details on what kind of failover you are trying to achieve?

Hi! I’ve used ds_select_dst() and ds_next_dst() one after another in failure route. If use in request/failure it’s working ok.

But again, during the failover in my environment dispatcher list can change. And I don’t want to rely on ds_next_dst() cause it can bring me absent node. So, I’ve been thinking of use xavp variable to get data from it, but still can’t get it to work.

I think you are confused between:

ds_select_dst() = get a node from the dispatcher group based on weight and priority. Use in request_route.

ds_next_dst() = get the next node from the list previously created with ds_select_dst(). Use this in failure_route.

Give it a try and let us know.

Is there any way to select not first destination from ds_select_dst()? Could not find any way to do this...

I just checked line 2285 in the code and it references the exact commit were avps changed to xavps.

I would definitely try 5.1 and open an issue in github.

Can you post your relevant config related to this in case something is just wrong there? (Both the request and failed route parts)

Hi

I think dispatcher changed from avps vars to xavps vars in master (5.2).

Can you try on latest stable (5.1) using avps instead just in case...?

Also, can you print in the logs the xavp_avp var you set in the modparam?

An example could be like this

3 nodes (A, B, C)

INVITE 1 -> ds_select_dst() -> Node A INVITE 2 -> ds_select_dst() -> Node A A dies B replaced C replaced

• external calls dispatcher.reload with new node list A (yes, died

state), E, F INVITE 1 -> failure_route, ds_mark_dst() as Disabled but with ds_next_dst() does not know anything about E or F, and B and C already out of order. So, my solution is again call ds_select_dst() in failure_route, but it can return Node A (which is dead and I know it already). So, I’m trying to select next node, with ds_next_dst() to select Node E, but calling this command gives me WARNING: dispatcher [dispatch.c:2285]: ds_update_dst(): no xavp uri field

If it brings the failed it’s because when it was marked as disabled that node was already in the list, so it will fail and hit the failure route again and move to next node.

The next call of ds_select_dst (in request route) will populate a list without disabled nodes, etc.

To summarize:

• In request route call ds_select_dst()
• if it fails, in failed_route call ds_mark_dst() and then ds_next_dst()

Example:

...to keep it easy to understand, let's pretend that dispatcher doesn't load balance and just failsover, let's say you have a ds group of nodes A, B and C...

• INVITE 1 received. ds_select_dst() (the list contains A, B, C). $du=A
• INVITE 2 received. ds_select_dst() (the list contains A, B, C). $du=A
• A dies.
• INVITE 1 in failure route, A is maked as disabled, ds_next_dst()

(updated list contains B and C). $du=B

• INVITE 3 received, ds_select_dst() (the list contains B, C). $du=B
• INVITE 2 in failure route, A is already marked as disabled, ds_next_dst()

(updated list contains B and C). $du=B

• ...people talk via server B because A failed...

So really you would only send calls that populated the dispather list before dying, after that the next calls wouldn't even try to hit that server.

Can you give some more details on what kind of failover you are trying to achieve?

Joel.

Hi! I’ve used ds_select_dst() and ds_next_dst() one after another in failure route. If use in request/failure it’s working ok.

But again, during the failover in my environment dispatcher list can change. And I don’t want to rely on ds_next_dst() cause it can bring me absent node. So, I’ve been thinking of use xavp variable to get data from it, but still can’t get it to work.

Regards, Igor On Sep 1, 2018, 4:33 PM +0200, Joel Serrano joel@textplus.com, wrote:

I think you are confused between:

ds_select_dst() = get a node from the dispatcher group based on weight and priority. Use in request_route.

ds_next_dst() = get the next node from the list previously created with ds_select_dst(). Use this in failure_route.

Give it a try and let us know.

Is there any way to select not first destination from ds_select_dst()? Could not find any way to do this...

Sorry, hit sent too soon.

I meant ds_next_dst() or ds_next_domain():

Try with ds_select_next() in failure_route[]

Tried other way round All of this is happening in FAILURE ROUTE.

ds_mark_dst("d"); ds_select_dst("1", "0")

But ds_select_dst still selecting for me gateway already marked with "d" on previous step. Seems, it applying states after packet sent. And any other way I can select new dst from set?

Idea why I'm using ds_select_dst in FAILURE_ROUTE and not ds_next_dst() that during failover timer dispatcher list could change (yes, it could be extensive process) and I want to use most fresh version.

Hello,

trying to summarize what you tried, because you say you do both:

ds_select_dst(...);

ds_next_dst();

in failure_route.

But if you do ds_select_dst(), then you already get the address of the gateway in the sip message structure, no need to call ds_next_dst(). Actually, if you do ds_next_dst() immediately after ds_select_dst(...), then practically you want to enforce second address selected for routing. Is this what you want to achieve?

To troubleshoot the warning message that uri xavp is not found, can you send logs with debug=3 and after each ds_select_dst(...) or ds_next_dst() add pv_xavp_print() to get the list of xavps? Use the latest master, I just pushed some commits that added more debug messages that should help troubleshooting better.

Cheers, Daniel

Can’t use 5.1 in my case, cause some of the features I’m ties to is only in 5.2 branch.  Anyway, I will check some other options, maybe move from dispatcher at all to some own-crafted solution.

I just checked line 2285 in the code and it references the exact commit were avps changed to xavps.

I would definitely try 5.1 and open an issue in github.

Can you post your relevant config related to this in case something is just wrong there? (Both the request and failed route parts)

Hi 

I think dispatcher changed from avps vars to xavps vars in master
(5.2). 

Can you try on latest stable (5.1) using avps instead just in
case...?

Also, can you print in the logs the xavp_avp var you set in the
modparam?

    An example could be like this

    3 nodes (A, B, C)

    INVITE 1 -> ds_select_dst() -> Node A
    INVITE 2 -> ds_select_dst() -> Node A
    A dies
    B replaced
    C replaced
     - external calls dispatcher.reload with new node list A
    (yes, died state), E, F
    INVITE 1 -> failure_route, ds_mark_dst() as Disabled
     but with ds_next_dst() does not know anything about E or F,
    and B and C already out of order.
    So, my solution is again call ds_select_dst() in
    failure_route, but it can return Node A (which is dead and I
    know it already). So, I’m trying to select next node, with
    ds_next_dst() to select Node E, but calling this command
    gives me

    If it brings the failed it’s because when it was marked as
    disabled that node was already in the list, so it will fail
    and hit the failure route again and move to next node. 

    The next call of ds_select_dst (in request route) will
    populate a list without disabled nodes, etc. 

    To summarize:

    - In request route call ds_select_dst()
    - if it fails, in failed_route call ds_mark_dst() and then
    ds_next_dst()

    Example:

    ...to keep it easy to understand, let's pretend that
    dispatcher doesn't load balance and just failsover, let's
    say you have a ds group of nodes A, B and C...

    - INVITE 1 received. ds_select_dst() (the list contains A,
    B, C). $du=A
    - INVITE 2 received. ds_select_dst() (the list contains A,
    B, C). $du=A
    - A dies.
    - INVITE 1 in failure route, A is maked as
    disabled, ds_next_dst() (updated list contains B and C). $du=B
    - INVITE 3 received, ds_select_dst() (the list contains B,
    C). $du=B
    - INVITE 2 in failure route, A is already marked as
    disabled, ds_next_dst() (updated list contains B and C). $du=B
    - ...people talk via server B because A failed...

    So really you would only send calls that populated the
    dispather list before dying, after that the next calls
    wouldn't even try to hit that server.

    Can you give some more details on what kind of failover you
    are trying to achieve?

    Joel.

        Hi!
        I’ve used 
        ds_select_dst() and ds_next_dst() one after another in
        failure route. 
        If use in request/failure it’s working ok.

        But again, during the failover in my environment
        dispatcher list can change. And I don’t want to rely on
        ds_next_dst() cause it can bring me absent node. 
        So, I’ve been thinking of use xavp variable to get data
        from it, but still can’t get it to work.

        I think you are confused between:

        ds_select_dst() = get a node from the dispatcher group
        based on weight and priority. Use in request_route. 

        ds_next_dst() = get the next node from the list
        previously created with ds_select_dst(). Use this in
        failure_route. 

        Give it a try and let us know.

                    ds_mark_dst("d");
                    ds_select_dst("1", "0")

                    But ds_select_dst still selecting for me

                     Idea why I'm using ds_select_dst in

                    during failover timer dispatcher list
                    could change (yes, it could be extensive

                            You could use pv_xavp_print():
                            https://www.kamailio.org/docs/modules/5.1.x/modules/pv.html#pv.f.pv_xavp_print

                            If there is a better way I'd like
                            to know myself.
