In Ganglia, I have configured a 2 clusters. cluster A has 2 nodes, cluster B has 13 nodes respectively. cluster B works well, while cluster A only has 1 node shown. The other node has exactly the same gmond.conf file, which is shown below:
globals {
daemonize = yes
setuid = yes
user = ganglia
debug_level = 0
max_udp_msg_len = 1472
mute = no
deaf = no
host_dmax = 0 /*secs */
cleanup_threshold = 300 /*secs */
gexec = no
send_metadata_interval = 0
}
cluster {
#name = "unspecified"
name = "rpt"
owner = "unspecified"
latlong = "unspecified"
url = "unspecified"
}
host {
location = "unspecified"
}
udp_send_channel {
#mcast_join = 239.2.11.71
host = qt-dw-master
port = 8557
ttl = 1
}
/*
udp_recv_channel {
#mcast_join = 239.2.11.71
port = 8557
#bind = 239.2.11.71
#bind = qt-dw-master
}
*/
tcp_accept_channel {
port = 8557
}
gmetad.conf on qt-dw-master is shown below:
data_source "rpt" 60 rpt0:8557 rpt1-db:8557
I have tried using multicasting, but does not work. I also want to find log files of gmond, but failed. Anyone can help on this problem?
Are all gmond running in the cluster A? Use commond service gmond status to confirm it

I'm trying to import a Linux VM Scale Set that was deployed in the Azure Portal from a custom shared image, also created in the portal. I'm using the following command:
terraform import module.vm_scaleset.azurerm_linux_virtual_machine_scale_set.vmscaleset /subscriptions/00000000-0000-0000-0000-000000000000
/resourceGroups/myrg/providers/Microsoft.Compute/virtualMachineScaleSets/vmss1
Import fails with the following error:
Error: retrieving Virtual Machine Scale Set "vmss1" (Resource Group "myrg"): properties.virtualMachineProfile.osProfile was nil
Below is my VM Scale set module code
data "azurerm_lb" "loadbalancer" {

The source image was created from a Linux RHEL 8.6 VM that included a custom node.js script.
Examination of the Scale Set in the portal does indeed show that the virtualMachineProfile.osProfile is absent.
I haven't been able to find a solution on any forum. Is there any way to ignore the error and import the Scale Set anyway?
I'm trying to spin up an Aurora Postgres Cluster and I can't seem to make it available over the internet. I'm using Terraform to code the infrastructure.
I've created a security group to allow external access and that is attached to the VPC's subnets used by the Cluster. Still, I can't seem to be able to access the endpoints from my local machine.
I can't figured out what I'm missing.
module "vpc" {
source = "terraform-aws-modules/vpc/aws"

name = "vpc-auroradb-${var.environment}"
cidr = var.vpc_cidr_block

enable_nat_gateway = true
enable_dns_hostnames = true
enable_dns_support = true
create_igw = true
create_database_internet_gateway_route = true
create_database_nat_gateway_route = true
create_database_subnet_group = true
create_database_subnet_route_table = true
}
module "aurora_cluster" {

name = "bambi-${var.environment}"
engine = "aurora-postgresql"
engine_version = "12.8"
instance_class = "db.t4g.large"
publicly_accessible = true
instances = {
1 = {
identifier = "bambi-1"
}
2 = {
identifier = "bambi-2"
}
}
autoscaling_enabled = true
autoscaling_min_capacity = 2
autoscaling_max_capacity = 3
vpc_id = module.vpc.vpc_id

}
resource "aws_security_group" "sg_public" {
vpc_id = module.vpc.vpc_id
ingress {
from_port = 5432
to_port = 5432
protocol = "tcp"
cidr_blocks = ["0.0.0.0/0"] # Allowing traffic in from all sources
}
egress {
from_port = 0 # Allowing any incoming port

}
}
From the documentation of the used VPC module, in order to have public access for the database, you need the following:
create_database_subnet_group = true
create_database_subnet_route_table = true
create_database_internet_gateway_route = true
enable_dns_hostnames = true
enable_dns_support = true
create_database_nat_gateway_route should not be true. If we take a look at the code for the module on github:
resource "aws_route" "database_internet_gateway" {
count = var.create_vpc && var.create_igw && var.create_database_subnet_route_table && length(var.database_subnets) > 0 && var.create_database_internet_gateway_route && false == var.create_database_nat_gateway_route ? 1 : 0
route_table_id = aws_route_table.database[0].id
destination_cidr_block = "0.0.0.0/0"
gateway_id = aws_internet_gateway.this[0].id
timeouts {
create = "5m"
}
}
We can see that the count for the route for the internet gateway will be 0. This means the route which would allow public internet access is not created for the database subnet.
In the other hand setting create_database_internet_gateway_route to true will block access through the NAT gateway as well, since the route table wont have the correct route.
resource "aws_route" "database_nat_gateway" {
count = var.create_vpc && var.create_database_subnet_route_table && length(var.database_subnets) > 0 && false == var.create_database_internet_gateway_route && var.create_database_nat_gateway_route && var.enable_nat_gateway ? var.single_nat_gateway ? 1 : length(var.database_subnets) : 0
route_table_id = element(aws_route_table.database.*.id, count.index)
destination_cidr_block = "0.0.0.0/0"
nat_gateway_id = element(aws_nat_gateway.this.*.id, count.index)
timeouts {
create = "5m"
}
}
Essentially you block all the traffic by setting both variables to true.
Currently I'm applying following terraform template in order to create kubernetes cluster, everything work as I expected.
module "subnet" {
source = "git::https://github.com/microsoft/bedrock//cluster/azure/subnet/?ref=master"
subnet_name = var.subnet_name
vnet_name = var.vnet_name
resource_group_name = data.azurerm_resource_group.keyvault.name
address_prefixes = [var.subnet_prefix]
}
module "aks-gitops" {
source = "git::https://github.com/microsoft/bedrock//cluster/azure/aks-gitops/?ref=master"
acr_enabled = var.acr_enabled
agent_vm_count = var.agent_vm_count
agent_vm_size = var.agent_vm_size
cluster_name = var.cluster_name
dns_prefix = var.dns_prefix
flux_recreate = var.flux_recreate
gc_enabled = var.gc_enabled
gitops_ssh_url = var.gitops_ssh_url
gitops_ssh_key_path = var.gitops_ssh_key_path
gitops_path = var.gitops_path
gitops_poll_interval = var.gitops_poll_interval
gitops_label = var.gitops_label
gitops_url_branch = var.gitops_url_branch
kubernetes_version = var.kubernetes_version
resource_group_name = data.azurerm_resource_group.cluster_rg.name
service_principal_id = var.service_principal_id
service_principal_secret = var.service_principal_secret
ssh_public_key = var.ssh_public_key
vnet_subnet_id = module.subnet.subnet_id
network_plugin = var.network_plugin
network_policy = var.network_policy
oms_agent_enabled = var.oms_agent_enabled
}
The next step in terrafrom is configure the CDN/Domain setup, and it requires the public IP address (which already created in above steps under module "aks-gitops") but the output seem to be not returned with that Ip address.
Any idea for that, since I've just dug all the resource on internet.
every comment is appreciated. !
Thank mates !
To retrieve the FQDN which resolves to the public IP of the cluster, create a data resource that references the newly created cluster.
data "azurerm_kubernetes_cluster" "aks-cluster" {
name = var.cluster_name
resource_group_name = data.azurerm_resource_group.cluster_rg.name
}
The address of the newly created cluster can then be accessed via data.aks-cluster.fqdn
You can follow a similar pattern to retrieve details of a load balancer, or any other resource that is not returned in the module outputs.
I have a Terraform config that I want to use to create VMs from a Vsphere template (Redhat 7) but I need to be able to specify the network interface to apply the customizations (static IP, Subnet, Gateway, DNS).
provider "vsphere" {
user = "${var.vsphere_user}"
password = "${var.vsphere_password}"
vsphere_server = "${var.vsphere_server}"
allow_unverified_ssl = true
}
resource "vsphere_virtual_machine" "vm1" {
name = "vm1"
folder = "${var.vsphere_folder}"
vcpu = 2
memory = 32768
datacenter = "dc1"
cluster = "cluster1"
skip_customization = false
disk {
template = "${var.vsphere_folder}/${var.template_redhat}"
datastore = "${var.template_datastore}"
type = "thin"
}
network_interface {
label = "${var.vlan}"
ipv4_address = "10.1.1.1"
ipv4_prefix_length = 16
ipv4_gateway = "10.1.1.254"
}
dns_servers = ["10.1.1.254"]
time_zone = "004"
}
I want to apply the static IP to bond0 instead of eth0, is this possible to do in Terraform?
Thanks.

I am new to kannel please help if i am doing anything wrong
You should check Kannel docs;
for a "normal" message, it will be "GSM" (coding=0), "binary" (coding=1) or "UTF-16BE" (coding=2)
What I see in url is that
&coding=0
what should be:
&coding=2
and also take care that it is url encoded correctly and about length of unicode message (if you are using aggregators not all support concatenation and long messages)
Hope it helps.
