LVM unavailable options
Richie765 opened this issue · 2 comments
Hello! I'm trying to use the LVM app. It looks well thought out and well documented. I got most of it working, like discovery. Many items work fine as well, but some don't.
When I looked into it, it seems my 'lvs' does not support some -o options, specifically: data_user, metadata_free, metadata_free_percent, data_free_percent, data_free. There may be more, but these are the ones I'd like to use.
They also don't show up in lvs -o help. I'm using lvm2 version 2.03 on Ubuntu. I also looked on a Centos server, but it looks like the options aren't there as well.
Are you using a different lvs tool? Do you have any idea how to make this working?
Thanks!
Hi @Richie765
Many items work fine as well, but some don't.
Which items ar not working and what error messages do you observe?
When I looked into it, it seems my 'lvs' does not support some -o options, specifically: data_user, metadata_free, metadata_free_percent, data_free_percent, data_free.
The mentioned items are calculated Zabbix items based on other Zabbix items, Thus, you can't use them directly as a parameter for lvs -o.
For example, the Free meta data of thin-pool LV {#LVM_LV_FULL_NAME} (rabe.lvm.lvs.value[{#LVM_LV_FULL_NAME},metadata_free,thin-pool]) item is calculated according to the following formula and items:
last("rabe.lvm.lvs.value[{#LVM_LV_FULL_NAME},lv_metadata_size,thin-pool]") - last("rabe.lvm.lvs.value[{#LVM_LV_FULL_NAME},metadata_used,thin-pool]")
In a first step, I would check that the items which are used within a calculated Zabbix item are working and data is available.
Ok, got it! In my template those items weren't calculated items. I re-imported the template and now it works fine. I don't know how it happened. I imported the template a while ago. Anyway it works fine now! Thanks, also for making this available. Very useful!
