Hello all, We're facing following issue. I noticed that there is some kind of bug with Kannel. We have high throughput with SMSC and that happens with all SMSCs and ESME connections.
The TPS is extremely low, around 2 TPS while for example we have 100 sms/s, or no limits if that comes to internal ESMEs. Below are our Kannel configs for internal ESME where this issue is urgent to be fixed (sensitive data was removed or replaced) - we do use commercial version of SMPPbox and bearerbox 1.5: 1) bearerbox.conf: group = core admin-port = 13000 admin-password = "" status-password = "" admin-allow-ip = "*.*.*.*" log-file = "/opt/kannel/var/log/bearerbox.log" log-level = 1 access-log = "/opt/kannel/var/log/access_bearerbox.log" box-deny-ip = "*.*.*.*" box-allow-ip = "127.0.0.1" smsbox-port = 13001 dlr-storage = mysql store-type = spool store-location = "/opt/kannel/var/spool/bearerbox" # define mysql receipt storage ## here are db configs ## ....... group = smsbox bearerbox-host = localhost bearerbox-port = 13001 sendsms-port = 13013 log-file = "/opt/kannel/var/log/smsbox.log" log-level = 0 access-log = "/opt/kannel/var/log/smsbox_access.log" http-request-retry = 3 http-queue-delay = 15 max-pending-requests = 2048 smsbox-id = smsbox1 2) smsc conf: group = smsc smsc = smpp smsc-id = smsc1 allowed-smsc-id = "smsc1;" host = <smppbox_host_ip> port = <smppbox_port> transceiver-mode = true smsc-username = smsc1 smsc-password = interface-version = 34 system-type = "VMA" log-level = 0 log-file = "/opt/kannel/var/log/smsc1.log" max-pending-submits = 348 # do not retry unacknowledged messages wait-ack-expire = 0x02 3) second server - smppbox.conf: group = smppbox admin-port = 14000 admin-password = status-password = coredump-location = "/opt/kannel/var/core" # SET YOUR OWN BEARERBOX HOST and DEFAULT SMSC-ID HERE! # bearerbox-host = "localhost" # # the following is to define inter-box charset encoding # bearerbox-dcs = latin1 for bearerbox < 1.4.3 # bearerbox-dcs = utf-8 for bearerbox => 1.4.3 # bearerbox-dcs = utf-8 smppbox-port = <smppbox_port> system-id = "<system-ID>" log-file = "/opt/kannel/var/log/smppbox.log" log-level = 0 access-log = "/opt/kannel/var/log/smpp_access.log" store-type = spool store-location = "/opt/kannel/var/spool/smppbox" # dlr storage, seperated from message spool dlr-store-type = spool dlr-store-location = "/opt/kannel/var/spool/dlr" # enable transparent MO routing # transparent-mo-routing = yes max-login-attempts = 100 response-mode = immediate 4) esme conf (that we use as smsc on another server): group = esme-user username = smsc1 password = default-smsc = "<smsc name>" max-instances = 15 # activate filtering if any plugin should apply for this user # filtering = yes # activate MO routing routing = yes # logging log-file = "/opt/kannel/var/log/esme_smsc1.log" log-level = 0 # receipting strict-dlr-routing = yes response-mode = immediate We were using 'SMPPBOX_THROUGHPUT' but it has been commented out. And this is how TPs looks like: smsc1[smsc1] SMPP:<host>:<port>/<port>:<smsc1>:VMA (online 58995s, rcvd: sms 0 (0.00,0.00,0.00) / dlr 17722 *(0.91,0.99,0.29*), sent: sms 48893 ( *1.56,1.14,0.81*) / dlr 0 (0.00,0.00,0.00), failed 1, queued 0 msgs) Now there is no queue but when it's there the TPS isn't growing more than 2 TPS. Our issue is same as posted there an year ago but nobody responded to it - http://kannel.6189.n7.nabble.com/EXtremely-Low-TPS-and-high-SMSC-queue-td32281.html Do you have any idea how to overcome that? Thank you in advance. ---- Best Regards,
