We have to take a look into this script, some weird things after testing that.

Page does not load properly, and stuff

I'll take a look

Hi,
I am experimenting that problem below now.

The backup script copies the resultant backup .tar.gz file to /backup however readme indicates it should be /backups
The docker-compose files also map /backups which then doesn't work as the backups are created within the container not in the mapped volume.

I'd submit changes, but I'm not sure if you'd prefer backup or backups to be used. It does contain multiple so the plural would make more sense. This would need the backup.sh to be updated and the readme.

The main cacti instance will auto-update remote pollers but not SPINE. Current upgrade script breaks permissions on remote polling aswell.

Initializing the DB is unsuccessful, resulting in Error 111, can't connect. The --port flag is missing from the statements.

Hi,

I can't log in in cacti. Is there any default user? Can I set it in installation?

Thanks

Does it make sense to store the RRAs in a persistent location so as to not have to rely on a backup scripts? If so, is the current storage location simply /cacti/rra?

/dev/tcp/localhosts/3306: cannot assign requested address

Hi Guys,

I'm new to docker so sorry for the odd questions.

I want to launch a container on my Synology device. But when I choose "Use the same network as Docker Host" I cannot change the port settings. I think this is the reason that I'm getting the following error's:

(98)Address already in use: AH00072: make_sock: could not bind to address [::]:80
(98)Address already in use: AH00072: make_sock: could not bind to address 0.0.0.0:80
no listening sockets available, shutting down
AH00015: Unable to open logs

Is it also possible to add port as a variable in the Advanced Settings? Or do I have anyother options?

I get this error when I try to install Cacti on my server.

cacti exited with code 1

Hi Sean, I was just going to try out the recent changes and seeing the following error after starting a test container with new volumes. I believe the www.sock file needs a permission change to either be owned by apache although I'm not completely sure.

How to add perl package for cacti container: perl-libwww-perl?
Can you give me some suggestions?

Hi,

I notice that new builds of spine don't have configure file so upgrades are applied just to Cacti. In Cacti dashboard error is displayed because cacti version is newer than spine.

To fix it i need to execute autoreconf -fvi and autoconf in order to generate the configure file.

hello,i use the docker cacti&mysql to used.
now cacti can display interface traffice graph,but cpu&memery can't display graph and the debug mode is no data.

Update compose to use network_mode: host due to remote poller checks, document why in Compose readme.

cacti.conf is static and appears to be overwritten on the first deployment. If a file exists don't overwrite.

Hello,

Very simple to replicate.
Go a head and compose up:

1. docker-compose -f cacti_multi_shared.yml up -d
2. Install cactimaster and cactipoller

Add any machine to the cactipoller, I get this error:

What I'm missing here?

Both fqdns are resolvable.. no problem in pinging those.

Hi
I've launched the docker-compose down and after up and the cacti has not worked anymore. Have you ever seen that issue?

Thanks

Any chance of getting this updated to the latest version of cacti?

Thanks!

Hello @scline ,

As reporterd here 4024 but I think they will not give too much attention, all possible connection is ok from container or host.

Whit this Image I cant send any email.

• Cacti Version 1.2.16
• Centos 8

I've build another one

• Cacti Version 1.2.16
• Centos 7 + ssmtp package and it works... without any specific config

Do you have anything on this matter?

Hi,

I've installed cacti in my k3s Kubernetes cluster, but the graphics are empty, just say "Failed to open data file, poller may not have run yet".

Should I mount the cacti data file into an external volume? I've also create a file inside /cact/rra and it works with the apache user or root user.

Finally, there are no error messages in the logs:

2021-01-05 23:00:03 - SYSTEM STATS: Time:1.3251 Method:spine Processes:1 Threads:1 Hosts:2 HostsPerProcess:2 DataSources:12 RRDsProcessed:0

Any tips?

Thanks,

Now $url_path = '/cacti/' is hardcoded in config.php. And there is no possibility to change it via an environment variable.
My proposal is to add CACTI_URL_PATH to have a possibility to change url_path. It is useful for Kubernetes with Ingress controller.

Documentation suggests it should be in the config directory.

good
when using the example with the compose using the suggested database, the installation process cannot create the "poller_output_boost" table due to an error with the timestamp format of the "time" field
I changed the image percona to mariadb:10.3, and this succeeded in creating the table without problems

Getting the following error and yes I'm using MySql 8.0.23 when installing the docker image.

ERROR 1045 (28000): Plugin caching_sha2_password could not be loaded: /usr/lib64/mariadb/plugin/caching_sha2_password.so: cannot open shared object file: No such file or directory

I'm using Cacti 1.2.17 from Docker hub smcline06/cacti, all settings are on their defaults (except added new devices and graphs).
I see ~14500 tables with the name poller_output_boost_arch_NNNNNN, and this makes DB slow, just due to the big directory size.
All of them are zero rows, but they aren't deleted automatically, so I had to delete them manually.
How this could be fixed?

As I'm not sure which project is responsible for this - I'm creating a bug in both, please see:
See Cacti/cacti#4535

Issues: Some setting which need to persist are being retained within the container, such that a container can not be re-created. This seems pretty fundamental, unless I'm missing something (sorry a bit new to Docker).

Reproduction Steps:

• Copy cacti_single_install.yml to docker-compose.yaml
• Edit docker-compose.yaml to change the ports which are in use (as 80 and 443 are already in use)

    ports:
      - "8282:80"
      - "8383:443"

• Run docker-compose up -d to create the cacti and database containers
• Open localhost:8282 and complete the configuration of cacti
• Make a change to the docker-compose.yml file. .e.g. Change the port again to say 8080 for cacti, or change the timezone, or add some additional labels (for example adding Traefik support).
• Re-run docker-compose up -d the cacti_cacti_1 container will be recreated.
• Navigate to localhost:8080 (if you changed the port) find you now get the Apache HTTP Server Test page, not Cacti. http://localhost:8080/cacti gives error not found.

We used this container to migrate an older version of Cacti on a new one.
We are using some scripts provided in perl language
These script failed with missing librabry on the container:
Can't locate Net/SNMP.pm in @inc (you may need to install the Net::SNMP module) (@inc contains: /usr/local/lib64/perl5 /usr/local/share/perl5 /usr/lib64/perl5/vendor_perl /usr/share/perl5/vendor_perl /usr/lib64/perl5 /usr/share/perl5) at /cacti/scripts/f5_bigip_cpun.pl line 5.
BEGIN failed--compilation aborted at /cacti/scripts/f5_bigip_cpun.pl line 5.
FATAL: Spine Encountered a Segmentation Fault

The package perl-Net-SNMP is missing in the container.
I added it manually, but it should be easier to have it directly in the default container

yum -y install perl-Net-SNMP.noarch

Thanks a lot
Regards.

Can you explain the proper way to change our db credentials but keep the data already collected?
I tested the default docker compose succesfuly,collected data and then after backing up with your script the data i deployed a new docker-compose file with different creds to a new VM and restored.It didnt start.

Then i copied the volumes and it starts correctly,thing is although the env vars are different i found its still using the default creds from your example and thats why its getting data.

The common error is Access denied for user 'cactiuser'@'172.21.0.3' (using password: YES)

Also i tried to change from inside the cacti docker manually the creds for the root and cactiuser users in the DB.I then noticed config.php kept the old creds so i changed it there too.Ofcourse im doing docker-compose down and up -d for my changes.

Still it keeps throwing the error and wont update the spine poller results.
SPINE: Poller[Main Poller] PID[1286] FATAL: Connection Failed, Error:'1045', Message:'Access denied for user 'cactiuser'@'172.21.0.3' (using password: YES)' (Spine parent)

I made combinations with initialize_db values but no luck.

Im missing something here,maybe another file that needs changing?Could you please reproduce and present the correct order of actions we need to do to change the DB credentials but keep the data?

May need to add the following to /etc/openldap/ldap.conf

REFERRALS       off
SSL             start_tls
TLS_REQCERT     allow

as the title says

It's any plan change back to 7 Or Other distribution? Cause CentOS 8 is going EOL

Using the cacti_single_install.yml docker-compose example. When bringing down/removing the containers with docker-compose down and restoring with docker-compose up -d the /spine/ directory is empty and original contents of the /etc/crontab is lost.

Hello,

Well I think is more of a question..
Do you guys have any problem conecting to a SMTP server from Cacti client on docker?

Host  --> I had tested from two sources, local/external both conects from telnet via cli with TLS enable or disabled.
Cacti Host --> Connects normaly to the server, all tests OK.

Container --> Also tested from two sources local/external both conects from telnet via cli with TLS enable or disabled.
Cacti Container --> It fails conection with SMTP normaly to the server, all tests NOT OK

I See traffic when I send a test email, but unable to connect from the container..

Cacti version 15 & 14
Docker version 19.03.10

Terminal / log:

AH00558: httpd: Could not reliably determine the server's fully qualified domain name, using 172.17.0.6. Set the 'ServerName' directive globally to suppress this message

And the container stops. I have temporarily added the following to start.sh to remediate, although might be best to add to Dockerfile on initial build?

echo "ServerName localhost" > /etc/httpd/conf.d/fqdn.conf

Hi.
I'm having trouble installing and configuring the syslog plugin.
what is the correct procedure to install and configure it?
i am missing the rsyslog-mysql part, how can i install it?
Thank you
