Just noticed, after digging around in the DB logs from my MQTT instrumentation, that the last spike correlated with a jump in data transferred out of the network interface:
Typical values are much less (see below), so this would seem to validate the "rouge bots hypothesis", currently leading the candidate to explain these periodic spikes:
This is also the first "hard correlation" of a spike with network interface iostats, so, let's see if my code in the post before this one will trap the next big spike
we have an unix system which has
load average normally about 20.
but while i am running a particular unix batch which performs heavy
operations on filesystem and database average load
reduces to 15.
how can we explain this situation?
while running that batch idle cpu time is about %60-65... (0 Replies)
Hello all, I have a question about load averages.
I've read the man pages for the uptime and w command for two or three different flavors of Unix (Red Hat, Tru64, Solaris). All of them agree that in the output of the 2 aforementioned commands, you are given the load average for the box, but... (3 Replies)
Hello, Here is the output of top command. My understanding here is,
the load average 0.03 in last 1 min, 0.02 is in last 5 min, 0.00 is in last 15 min.
By seeing this load average, When can we say that, the system load averge is too high?
When can we say that, load average is medium/low??... (8 Replies)
Hi,
i have installed solaris 10 on t-5120 sparc enterprise.
I am little surprised to see load average of 2 or around on this OS.
when checked with ps command following process is using highest CPU. looks like it is running for long time and does not want to stop, but I do not know... (5 Replies)
Hello AlL,..
I want from experts to help me as my load average is increased and i dont know where is the problem !!
this is my top result :

Hi ,
I am using 48 CPU sunOS server at my work.
The application has facility to check the current load average before starting a new process to control the load.
Right now it is configured as 48. So it does mean that each CPU can take maximum one proces and no processe is waiting.

Hi,
I am getting a high load average, around 7, once an hour. It last for about 4 minutes and makes things fairly unusable for this time.
How do I find out what is using this. Looking at top the only thing running at the time is md5sum.
I have looked at the crontab and there is nothing... (10 Replies)

net_phylookup
net_phylookup(9F) Kernel Functions for Drivers net_phylookup(9F)NAME
net_phylookup - determine if a network interface name exists for a network protocol
SYNOPSIS
#include <sys/neti.h>
phy_if_t net_phylookup(const net_data_t net, const char *name);
INTERFACE LEVEL
Solaris DDI specific (Solaris DDI).
PARAMETERS
net value returned from a successful call to net_protocol_lookup(9F).
name name of the network interface to find.
DESCRIPTION
The net_phylookup() function attempts to resolve the interface name passed in with the network protocol.
When called successfully, the value returned represents a network interface that exists, at the time of the call, within the scope of the
network interface. This value is only guaranteed to be unique for a name within the scope of the network protocol.
RETURN VALUES
The net_phylookup() function returns -1 if it is not supported by the network protocol, and 0 if the named network interface does not
exist (or is otherwise unknown). Otherwise, it returns a value greater than 0 representing a network interface that currently exists
within the scope of this network protocol.
CONTEXT
The net_phylookup() function may be called from user, kernel, or interrupt context.
