how to send logs from TG585v7 to syslog server ?

I have a PN TG585v7 (8.2.6.5). I would like to transmit its logs in real-time to a server on my network.
I can do it one-shot from the CLI like this

{admin}=> systemlog send hist=enabled dest=10.255.255.255

However I would like to do it in real-time. I've searched and found this but I am not having any success.
Does anyone know how to do this ?

This may help:
http://npr.me.uk/telnet.html#syslog
If you're hoping for SNMP type reports you'll be disappointed, R8 firmware for that router doesn't have a SNMP server.
IIRC  R7 firmware may have a SNMP server.

Thanks, although I don't have a "syslog" command:

In that case I think you're out of luck with that router, or you could try a earlier R7 firmware to see if that runs a SNMP server.
As suggested in your link, you could try a telnet script to periodically request the log, with the command you have, but I suspect that will keep reproducing a lot of the same information each time it's run.
You can find details of using a windows telnet scrip here:
http://npr.me.uk/scripting.html
If using linux, have a look at using "spawn" and "netcat" (nc), I've used those commands successfully in the past for telnet scripts run on a Raspberry Pi.

Re: how to send logs from TG585v7 to syslog server ?

Hi, thanks. I've done a fair bit of telnet scripting for this router already (see here if you're interested).
My rationale for doing this was to get to the bottom of some spontaneous reboots but the local log doesn't seem to persist across reboots despite my trying. I can get the ad-hoc method to work fine but it requires messing about and won't help capture those final messages prior to a reboot.
Maybe it's time to change routers. I have a tp-link td-w8961 that I can swap in. I've been reluctant so far after investing so much effort in getting to the bottom of how much of the speedtouch works, despite it being so bad in many respects.

Re: how to send logs from TG585v7 to syslog server ?

Well I've played around a bit more today. The "systemlog send" method that I described before sends the entire log but it does so without line breaks. This requires a bit of messing around on the server to store the log cleanly. I do, however, now have a listener set up that dumps whatever the router sends into the systemd journal. I can use a timer or cron job to kick the router (via telnet) into sending the current log and then flushing.
I'd still be interested in knowing if there is a proper way to configure the router to send to a syslog server in real time. Any PN staffers (or anyone else!) know the answer to this?
