Want to send traffic info to Zabbix little flash space

[jany]

This is my router and I only have 52KiB free.

I need to measure traffic on the WAN interface.
On the other hand, I would like to store the data on the zabbix server.
Do I have any options?

Are you asking how to install the Zabbix agent?

It is 8/64 device, since you stuffed overlay with irrelevant garbage you dont have any space for zabbix (or smaller snmp) agents.

Easiest way to recover is to sysupgrade, then do updates via luci-app-attendedsysupgrade to move installed pacjkages to commpressed squashfs /rom

[jany]

No, I don't have any more space to install it. I need some way to store information about transferred data. It doesn't have to be a zabbix server (but I can also use a zabbix server).
I read that there is, for example, nlbwmon, but I have little space.
I know that it is possible to expand the storage using a USB key, but I don't have a USB key right now.

Hope you have room for the dependencies.

I only installed wireguard in openwrt and nothing else. The other space can be used for an LTE modem.

You should upgrade to 23.05.5.

You're pretty tight on space, so I think your options are limited.

You will probably need to use the firmware selector to pre-install the packages you need as well as remove the packages you don't. By creating an image with the packages pre-installed, you will save space relative to installing the packages after you've flashed your router (this is because the firmware is compressed).

https://openwrt.org/faq/no_space_left_on_device

Even with the process of removing some packages and using the firmware selector to pre-install packages, it's possible you still won't have enough room. If that's the case, there's nothing more you can realistically do except get a new device that has more storage.

The OP's device does not have USB. Extroot is not an option.

Then, how, what?

Okay.

You can force sysupgrade with auc command to move wg to compressed squashfs. Or maybe compose image with necessary packages via firmware-selector.

• You may be able to use the Firmware Selector to add the agent to the image (might fit pre-build)
• The softflowd package can record traffic flows - but I'm not sure how much space that takes, puls you'll need a collector server
• Using the firewall to log may ben an option

[jany]

I decided not to monitor traffic due to low storage space.
Thank you all for your valuable advice.

[psherman]

Glad we could help, despite the fact that we weren't able to actually make it possible to fit everything you wanted in the limited storage space on your device.
