LPAR2RRD monitoring XCP-ng
Hello.
I made a new install of lpar2rrd 7.20 on a CentOS 7 VM to monitor XCP-ng, a Citrix Xenserver fork/derivative.
Had run the install.sh script and configured passwordless ssh access to the root user of the 7 XCP-ng servers of one pool.
But do not matter what I try, I can't have the web interface to show the left menu, where I could select XCP objects to graph (please see second picture).
I have seven XCP/Xen hosts of a pool configured (please see first picture)
What can I do to debug what is causing this lack of the expected menu forming below "Reporter" link at the left side of screen?
Thank you.
Antonio

Hello,
- when you run the Connection test, does it succeed?
- corresponding menu folder appears only after (1) data have been fetched from the host (
load_xenserver.sh) and then (2) the new menu has been created (load.shorload.sh htmlrespectively); these scripts are scheduled in crontab and so it may take a while before the changes take effect (about an hour or the next day at most).
If the previous steps fail, we will investigate further.

Hello, David!
All 7 connection testes give feedback similar to the picture below.

load_xenserver.sh appears to be collecting data, as the rrd files are being created, as the following directory listing example.[lpar2rrd@ohm lpar2rrd]$ ll -Rh data/XEN*data/XEN:total 28Kdrwxr-xr-x. 2 lpar2rrd lpar2rrd 4.0K Jul 1 16:55 1db36d96-41e3-4728-9015-f50cdef3a5f5drwxr-xr-x. 2 lpar2rrd lpar2rrd 4.0K Jul 1 16:55 1e4e0073-194e-4f76-92db-c7e6a77dff39drwxr-xr-x. 2 lpar2rrd lpar2rrd 4.0K Jul 1 14:20 6b424e4b-cfba-4b0a-a856-4ce0f04c027cdrwxr-xr-x. 2 lpar2rrd lpar2rrd 4.0K Jul 1 16:55 7031970d-fa54-4b01-a42f-61dc4cedfc1fdrwxr-xr-x. 2 lpar2rrd lpar2rrd 4.0K Jul 1 16:55 9b55def1-dd35-498b-8183-597bf5c6b040drwxr-xr-x. 2 lpar2rrd lpar2rrd 4.0K Jul 1 16:55 bcb6844e-311d-4f4e-9ac6-ea835ebbeae4drwxr-xr-x. 2 lpar2rrd lpar2rrd 4.0K Jul 1 16:55 cc20f424-9327-4684-bb7e-64a156894890data/XEN/1db36d96-41e3-4728-9015-f50cdef3a5f5:total 135M-rw-r--r-x. 1 lpar2rrd lpar2rrd 11M Jul 7 08:35 disk-099bc12c.rrd-rw-r--r-x. 1 lpar2rrd lpar2rrd 11M Jul 7 08:35 disk-108f25a1.rrd-rw-r--r-x. 1 lpar2rrd lpar2rrd 11M Jul 7 08:35 disk-14e4c435.rrd-rw-r--r-x. 1 lpar2rrd lpar2rrd 11M Jul 7 08:35 disk-213cf063.rrd-rw-r--r-x. 1 lpar2rrd lpar2rrd 11M Jul 7 08:35 disk-263bf264.rrd-rw-r--r-x. 1 lpar2rrd lpar2rrd 11M Jul 7 08:35 disk-3ecdad19.rrd-rw-r--r-x. 1 lpar2rrd lpar2rrd 11M Jul 7 08:35 disk-4b75ed35.rrd-rw-r--r-x. 1 lpar2rrd lpar2rrd 11M Jul 7 08:35 disk-62dda264.rrd-rw-r--r-x. 1 lpar2rrd lpar2rrd 11M Jul 7 08:35 disk-73fe8768.rrd-rw-r--r-x. 1 lpar2rrd lpar2rrd 11M Jul 7 08:35 disk-934429c1.rrd-rw-r--r-x. 1 lpar2rrd lpar2rrd 11M Jul 7 08:35 disk-d899f874.rrd-rw-r--r-x. 1 lpar2rrd lpar2rrd 11M Jul 7 08:35 disk-f5f88af2.rrd-rw-r--r-x. 1 lpar2rrd lpar2rrd 1.9M Jul 7 08:35 lan-bond0.rrd-rw-r--r-x. 1 lpar2rrd lpar2rrd 1.9M Jul 7 08:35 lan-eth0.rrd-rw-r--r-x. 1 lpar2rrd lpar2rrd 1.9M Jul 7 08:35 lan-eth1.rrd-rw-r--r-x. 1 lpar2rrd lpar2rrd 1.9M Jul 7 08:35 lan-eth2.rrd-rw-r--r-x. 1 lpar2rrd lpar2rrd 1.9M Jul 7 08:35 lan-eth3.rrd-rw-r--r-x. 1 lpar2rrd lpar2rrd 4.6M Jul 7 08:35 sys.rrd<some listings cut off to conserve space>data/XEN_iostats:total 4.0K-rw-r--r-x. 1 lpar2rrd lpar2rrd 3 Oct 8 2019 conf.jsondrwxr-xr-x. 2 lpar2rrd lpar2rrd 6 Jul 7 08:35 jsondrwxr-xr-x. 2 lpar2rrd lpar2rrd 6 Jul 2 00:15 metadatadrwxr-xr-x. 2 lpar2rrd lpar2rrd 6 Jul 7 08:20 xmldata/XEN_iostats/json:total 0data/XEN_iostats/metadata:total 0data/XEN_iostats/xml:total 0data/XEN_VMs:total 1.6G-rw-r--r-x. 1 lpar2rrd lpar2rrd 18M Jul 7 08:35 0388a3ac-d017-e38b-1ffe-48130d318c20.rrd-rw-r--r-x. 1 lpar2rrd lpar2rrd 18M Jul 7 08:35 06d4b63c-007c-cd45-7545-f560b56a08ef.rrd-rw-r--r-x. 1 lpar2rrd lpar2rrd 18M Jul 7 08:35 079d2582-f17b-315d-38f7-66d11ea2b2b4.rrd-rw-r--r-x. 1 lpar2rrd lpar2rrd 18M Jul 7 08:35 0c976578-f5a3-ea3c-e14c-9f40e7fb87e3.rrd-rw-r--r-x. 1 lpar2rrd lpar2rrd 18M Jul 7 08:35 0d9124ba-6ff7-ea91-08eb-879c951241a3.rrd-rw-r--r-x. 1 lpar2rrd lpar2rrd 18M Jul 7 08:35 0f9f2e70-7415-9b07-824f-430e86287480.rrd<some listings cut off to conserve space>--//--

In this same CentOS VM, named Ohm, I run stor2rrd com great success. Many years now.

Thank you for the details. The crucial file for creating a XenServer menu is
data/XEN_iostats/conf.jsonwhich exists; can you check if it isn't effectively empty? (No need to paste the contents here if it has necessary data, because it would be too large and contain details about your setup.) A backup copy should betmp/xenserver-conf-last.json, but that is missing from your listing. -
Hi David. You found it - the file is almost empty. Contains only {} on a line by itself.
Do you know how I can properly config this file, please? -
I suspect there is a problem with fetching or merging the configuration data (will post an update). For the record, what XCP-ng version do you use?
-
I use XCP-ng version 8.2 LTS. Thank you.
-
Please, let me know if I could be of any help, to test anything, or provide new data. Thank you.

Hello,
can you try the following patch? It restructures some of the queries over SSH to reduce overhead.
https://download.lpar2rrd.com/patch/7.21-2-9-g2336e/xen-xapi2json.pl.gz
Gunzip it and copy to
/home/lpar2rrd/lpar2rrd/bin(755, lpar2rrd owner)-rwxrwxr-x 1 lpar2rrd lpar2rrd 17453 19. čec 13.11 xen-xapi2json.pl
If your web browser gunzips it automatically then just rename it:
mv xen-xapi2json.pl.gz xen-xapi2json.plAssure that file size is the same as on above example.
-
Hi David! The patch does work! Thanks!
Some graphs do not show, and I'll try later in the day. One of interest to me is storage activity. That fails, I think, because the guest tools file in /opt/xensource/iso/guest-tools-8.2.0-2.xcpng8.2.iso[12:15 uaaxcpngp01h01 ~]# xe sr-list uuid=aba8434e-7608-f711-466b-be2cf2e1ac0buuid ( RO) : aba8434e-7608-f711-466b-be2cf2e1ac0bname-label ( RW): XCP-ng Toolsname-description ( RW): XCP-ng Tools ISOshost ( RO): <shared>type ( RO): isocontent-type ( RO): iso

Is there an easy way to avoid the guest tools ISO file to be entered into the storage resources data collection or in the graph data plot under pool's storage resources?
-
Hello,
does the XCP-ng Tools ISOs storage (or any storage in the menu whose graphs do not show like this) have a corresponding RRD file anywhere in
data/XEN/? It might be that the storage is<shared>on the XAPI-side, but only some hosts actually report its performance metrics.More generally, it would be straightforward to skip storage of type
isoaltogether, it already works that way, for example, in the Configuration > Storage tables. Would you consider that better, or are there any ISOs whose performance data interests you? -
Hi David, thank you for helping me. We consider iso performance of less interest than the storage resources that contain vms. We only use isos to install lguest utilities and store files used in the vm installation process, so is a little percent of use compared to production.
I'll try to configure as you told me to do. Thank you. -
Reporting back, the specific storage the gives the error in the above picture, have rrd files under some of the xcp-ng hosts directories (there are 7 hosts/dirs), but not all of them. Different files, with the same names.
-
Reporting again, the Configuration > Storage tab tables show greatly detailed information.
For each xcp-ng host there is a line containing an particular xcp-ng storage resource and it contained VDI (volume).
Since we use all the production vms into shared storage resources, I'd find more useful to group data for each storage resource, along with its contents.
We have 01 local storage on each of the 07 hosts, and 14 SRs shared to the 7 hosts. So the table generation for the web page takes a long time to show. I included part of the long listing in that web page.
-
The particular SR that gives problems when graphing (disk-aba8434e)
, is not listed into the configuration > storage tab.

Hello,
thank you for the information.
If you use the following patch, any storages that are omitted in Configuration (mainly ISO) will be omitted from newly created menu too (file
tmp/menu_xenserver.json; if you delete it, you can immediately force creating it anew by calling./load.sh htmlin thelpar2rrddirectory).https://download.lpar2rrd.com/patch/7.21-5-3-g22a3/xen-genmenu.pl.gz
Gunzip it and copy to
/home/lpar2rrd/lpar2rrd/bin(755, lpar2rrd owner)-rwxrwxr-x 1 lpar2rrd lpar2rrd 7974 29. čec 10.37 xen-genmenu.pl
If your web browser gunzips it automatically then just rename it:
mv xen-genmenu.pl.gz xen-genmenu.plAssure that file size is the same as on above example.
-
Oh, thank you for this patch. Only saw it today, as I had the news that lpar was updated to 7.30. Thank you!
Howdy, Stranger!
