Hi,

brutevinch commented 7 years ago

1) Modbus TCP 2) Zabbix 3.0 3) current Timeout is set to 10

v-zhuravlev commented 7 years ago
brutevinch commented 7 years ago
  1. selfmade modbus tcp -> modbus rtu gateway on esp8266 (OpenHab polling fine without any problems)
  2. last from master branch
brutevinch commented 7 years ago

Here is openhab config (maybe it can help you)

poll=30000 writemultipleregisters=true

tcp.sdm230_Voltage.connection=10.0.1.23:502:0 tcp.sdm230_Voltage.type=input tcp.sdm230_Voltage.valuetype=float32 tcp.sdm230_Voltage.length=2 tcp.sdm230_Voltage.start=0 tcp.sdm230_Voltage.id=1

v-zhuravlev commented 7 years ago

It might be related to resource locking (there is no for TCP).

Can you try the following patch https://github.com/v-zhuravlev/libzbxmodbus/tree/TCP-always-lock (with locking enabled for TCP as well)?

git clone -b TCP-always-lock --recursive https://github.com/v-zhuravlev/libzbxmodbus.git Run autogen.sh ./configure --prefix=/etc/zabbix --enable-zabbix-3 make make install

brutevinch commented 7 years ago

2017-06-02 15 28 42 Same thing =(

v-zhuravlev commented 7 years ago

  1. Ok, to 100% make sure it has nothing to do with resource sharing: In your Zabbix server (if it is possible to do so) please leave only single poller: StartPollers=1 and restart.

  2. can you also run ipcs -s while your Zabbix server with module loaded is runnning? and show me the output of it.

brutevinch commented 7 years ago
  1. done

  2. 2017-06-02 15 49 55

P.s. zbx agent working on same machine.

v-zhuravlev commented 7 years ago

Strange, accodring to this it looks like that you might be using old version (<0.6) of the module anyway. In the new version you must see zabbix semaphore with nsems = 128 and not 1.

Try deleting your old modules from (/usr/local/lib i suppose) and in zabbix server config point to the new location:

LoadModulePath = /etc/zabbix/lib

Restart server. Check that ipcs -s shows you the semaphore with nsems = 128. If not going to work, which linux distro do you use?

brutevinch commented 7 years ago

Here is with new module: 0x7a021f65 655365 zabbix 600 128

in zabbix 2 of 3 data sources are "Connection timed out"

/usr/src # cat /etc/debian_version
8.7

chroot debian for Synology

v-zhuravlev commented 7 years ago

even with single poller?

brutevinch commented 7 years ago

Ну если 1 поллер включается добавлением в конфиг сервера то да. Вот кусок конфига сервера: LoadModulePath = /etc/zabbix/lib LoadModule = libzbxmodbus.so Timeout = 10

StartPollers=1

v-zhuravlev commented 7 years ago

uff....weird.

Ok, lets try it again:

git clone -b debug_enabled --recursive https://github.com/v-zhuravlev/libzbxmodbus.git Run autogen.sh ./configure --prefix=/etc/zabbix --enable-zabbix-3 make make install

Then in configuration file:

LogType=console
DebugLevel=1

In zabbix frontend: Disable all modbus items and leave only one active.

Stop the zabbix-server rerun it with in the foreground: zabbix_server -f

You should now see all the modbus debug messages from the libmodbus lib. Please attach it here. They should contain a part where it fails also.

v-zhuravlev commented 7 years ago

You don't have any errors/timeouts with single item?

brutevinch commented 7 years ago

testing now. tell you later

v-zhuravlev commented 7 years ago

ok. If there are no issues with single item -> try reenabling them

It looks like that there is still more than one poller. Maybe do you have another StartPollers somewhere in the config file with not 1? try: in your debug_enabled repo: git pull make install new logging of zabbix_server -f now should provide pid of the process.

how did you implement Modbus TCP server? It this your own code?

Here is gateway code

modbus_gate_v2.lua.zip

v-zhuravlev commented 7 years ago

selfmade modbus tcp -> modbus rtu gateway on esp8266 (OpenHab polling fine without any problems)

Could it be that OpenHab actually also sometimes receive invalid data/timeout? Just it doesn't show you that?

brutevinch commented 7 years ago

Saw openhab traces. There is no errors and warnings and all data received every 30 sec without any errors too. =(

brutevinch commented 7 years ago

Every 30 sec.

So let's sum ip what we have:

v-zhuravlev commented 7 years ago

try with disabled byte timeout:

in your debug_enabled repo: git pull make install

brutevinch commented 7 years ago

Hi, now I see some errors in openhab, please give some time to test it.

brutevinch commented 7 years ago

Sorry it was unstable buggy code.

v-zhuravlev commented 7 years ago

@brutevinch , Did you fix it? Is it working with libzbxmodbus now? With(debug branch) or without(current main branch) TCP locking?

brutevinch commented 7 years ago

Rewrite gateway code to mqtt.
