When I try to import the template (by the way the file name is now different on your github than the instructions show) I get this error in zabbix, Cannot read XML: (41) Specification mandate value for attribute data-pjax-transient [Line: 43 | Column: 40].

I am running Zabbix 3.4 on Centos 7. See attached image for details....

Should be:

<name>RAID array device MD {#MD_RAID_RAID_DEV_NAME} has {ITEM.VALUE1} degraded device(s) on {HOST.NAME}</name>

I don't know if you get that much feedback, I just wanted to point out that the LVM template works like it should in Zabbix 4.0 (on the zabbix-share site of the project it mentioned Zabbix 3.0.x)

Cheers!

IN the template i see only one discovery rule: "LVM thin pool discovery" key lvm[discovery], which is not there in the agent config.

Hallo,
discovered your work on share.zabbix.com.
I downloaded the script and tried to run if from shell, but it fails immediately. Any idea why this happens?
Thank you!

EDIT: I'm on Debian 9 Stretch amd64 with Zabbix 3.4.x
If I comment out line 47 the script seems to work.

It would be useful if the MD-RAID template reported the number of spare disks available.

So I have ubuntu 20.04 with raid0

 mdadm -D /dev/md0

I copied your userparameter_md.conf file into /etc/zabbix/zabbix_agentd.d folder . For the servers that have configured raid1 - this parameter works well:
UserParameter=custom.md.discovery,cat /proc/mdstat | grep -B 1 -E "(U+|_+)" | awk 'BEGIN { printf "{\"data\":["}; /^md/ { printf c"{\"{#MDNAME}\":\""$1"\"}";c=","}; END{ print "]}" }'

But I have raid0 and this grep cat /proc/mdstat | grep -B 1 -E "(U+|_+)" not parsed it. It returned NULL, because it parse UU that is not used for raid0.
And if you try to use this user parameter:
UserParameter=custom.md.discovery,cat /proc/mdstat | awk 'BEGIN { printf "{\"data\":["}; /^md/ { printf c"{\"{#MDNAME}\":\""$1"\"}";c=","}; END{ print "]}" }' - zabbix will parse raid0 devices.

I have installed this template under zabbix 4.0 and tested it with a Ubuntu 16.04 client (zabbix-agent) using mdadm raid 10. After installing the client config and resetting the zabbix agent on the client there are no errors in the agent log but I don't see any data relating to mdadm when I check out the "Latest data" page for the mdadm using zabbix client.

I get this problem popping up all the time:

CPU is measured in kbps (or am i wrong and thats ok?) like this:

I doubt cpu usage is always over 90%... Or do you know a method to check cpu utilization on this switch?

Can you advise please? cant upgrade my existing zabbix server yet.

Some new policy seems to have been enforced and sudo (in UserParameters) for things like some app/lvm template are getting denied.

The new(?) SELinux bools don't seem to work. I tried:

setsebool zabbix_run_sudo=1
setsebool domain_kernel_load_modules=1

The current workaround is to semanage permissive -a zabbix_agent_t until we can fix our rabezbxzabbixagent SELinux module to let the zabbix user use sudo to run things like lvs.

On some investigation I found that this might be specific and due to how our pam stack is configured as the servers are configured as part of a freeipa domain.

I'm preparing a pr to address this and it should be ready after some more testing.

Value of type "string" is not suitable for value type "Numeric (unsigned)". Value "cat: /sys/block/md0/md/degraded: No such file or directory

File is not exist because it's not used for raid0.

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!

We need a way to generate the documentation for IPMI, OS, SNMP and Stack templates, as we currently do for the App templates.

• IPMI templates (addressed and merged with #29)
• OS templates (addressed and merged with #38)
• SNMP templates (addressed with 8934b4a, 60d7c85 and c8f184f)
• Stack templates

I saw that the package is available for CentOS. Do you think it would work on Debian as well? We could really use that, but our system is on Debian.

When using your script in Zabbix 3.4 it gets the following error: Value should be a JSON object." I don't think the output of your script produces a properly JSON formatted output anymore with the changes in LLD rules now in Zabbix 3.4. This seems to be an issue now with all your scripts, not just this one.

Could you check?

I have successfully got your MD-RAID template to work under Zabbix 4.0 but I had to change a few settings to use passive instead of active monitoring. I think the MD-RAID README should be updated with instructions on how to do this because its not at all obvious (to Zabbix newbs) and it took me a while to work it out / remember how to do it.

There may be a better way to do it but I used these steps (after following the existing installation instructions):

Under the Zabbix web interface go to Configuration -> Hosts -> then click 'Discovery' next to the relevant host. Now click 'Item prototypes' next to the 'RAID device (MD) discovery' rule then click on each of the 5 item prototypes and change the Type of all 5 Raid device item prototypes from 'Zabbix agent (active)' to 'Zabbix agent'.

Hello,

I setup this wonderful plugin successfully. However, there is not alerts triggered even if I manually set a disk to faulty state.

My Zabbix Agent is used in passive mode so I just changed "Zabbix Agent (active)" to "Zabbix Agent" in discovery templates settings.

Here's the output of few debug commands :

su -c 'zabbix_agentd -t rabe.raid.md.raid-device.discovery' -s /bin/bash zabbix
rabe.raid.md.raid-device.discovery [t|{"data":[{"{#MD_RAID_RAID_DEV_NAME}":"md0"}]}]

Am I doing anything wrong ?

Thank you :)

I couldnt find template for the power reading. For example ipmitool can be used as follows:

# ipmitool dcmi power reading

    Instantaneous power reading:                   197 Watts
    Minimum during sampling period:                175 Watts
    Maximum during sampling period:                242 Watts
    Average power reading over sample period:      190 Watts
    IPMI timestamp:                           Sun Mar  6 15:13:42 2022
    Sampling period:                          00123893 Seconds.
    Power reading state is:                   activated

Is there a way to get this information from your templates?
